1.1 Summary
===========

Org-mode is a mode for keeping notes, maintaining ToDo lists, and doing
project planning with a fast and effective plain-text system.

   Org-mode develops organizational tasks around NOTES files that
contain information about projects as plain text.  Org-mode is
implemented on top of outline-mode, which makes it possible to keep the
content of large files well structured.  Visibility cycling and
structure editing help to work with the tree.  Tables are easily
created with a built-in table editor.  Org-mode supports ToDo items,
deadlines, time stamps, and scheduling.  It dynamically compiles
entries into an agenda that utilizes and smoothly integrates much of
the Emacs calendar and diary.  Plain text URL-like links connect to
websites, emails, Usenet messages, BBDB entries, and any files related
to the projects.  For printing and sharing of notes, an Org-mode file
can be exported as a structured ASCII file, as HTML, or (todo and
agenda items only) as an iCalendar file.  It can also serve as a
publishing tool for a set of linked webpages.

   Org-mode keeps simple things simple.  When first fired up, it should
feel like a straightforward, easy to use outliner.  Complexity is not
imposed, but a large amount of functionality is available when you need
it.  Org-mode can be used on different levels and in different ways, for
example:

     * as an outline extension with visibility cycling and structure editing
     * as an ASCII system and table editor for taking structured notes
     * as an ASCII table editor with spreadsheet-like capabilities
     * as a TODO list editor
     * as a full agenda and planner with deadlines and work scheduling
     * as a simple hypertext system, with HTML export
     * as a publishing tool to create a set of interlinked webpages

   The Org-mode table editor can be integrated into any major mode by
activating the minor Orgtbl-mode.

   There is a website for Org-mode which provides links to the newest
version of Org-mode, as well as additional information, frequently asked
questions (FAQ), links to tutorials etc.  This page is located at
`http://www.astro.uva.nl/~dominik/Tools/org/'.

File: org,  Node: Installation,  Next: Feedback,  Prev: Summary,  Up: Introduction

1.2 Installation and Activation
===============================

If Org-mode is part of the Emacs distribution or an XEmacs package, you
only need to copy the following lines to your `.emacs' file.  The last
two lines define _global_ keys for the commands `org-store-link' and
`org-agenda' - please choose suitable keys yourself.

     ;; The following lines are always needed.  Choose your own keys.
     (add-to-list 'auto-mode-alist '("\\.org$" . org-mode))
     (define-key global-map "\C-cl" 'org-store-link)
     (define-key global-map "\C-ca" 'org-agenda)

   Furthermore, you must activate `font-lock-mode' in org-mode buffers,
because significant functionality depends on font-locking being active.
You can do this with either one of the following two lines:
     (global-font-lock-mode 1)                     ; for all buffers
     (add-hook 'org-mode-hook 'turn-on-font-lock)  ; org-mode buffers only

   If you have downloaded Org-mode from the Web, you must take
additional action:  Byte-compile `org.el' and `org-publish.el' and put
them together with `org-install.el' on your load path.  Then add to
`.emacs':

     ;; This line only if org-mode is not part of the X/Emacs distribution.
     (require 'org-install)

   If you use Org-mode with XEmacs, you also need to install the file
`noutline.el' from the `xemacs' subdirectory of the Org-mode
distribution.

   With this setup, all files with extension `.org' will be put into
Org-mode.  As an alternative, make the first line of a file look like
this:

     MY PROJECTS    -*- mode: org; -*-

which will select Org-mode for this buffer no matter what the file's
name is.  See also the variable `org-insert-mode-line-in-empty-file'.

1.3 Feedback
============

If you find problems with Org-mode, or if you have questions, remarks,
or ideas about it, please contact the maintainer Carsten Dominik at
<dominik@science.uva.nl>.

   For bug reports, please provide as much information as possible,
including the version information of Emacs (`C-h v emacs-version
<RET>') and Org-mode (`C-h v org-version <RET>'), as well as the
Org-mode related setup in `.emacs'.  If an error occurs, a traceback
can be very useful.  Often a small example file helps, along with clear
information about:

  1. What exactly did you do?

  2. What did you expect to happen?

  3. What happened instead?
        Thank you for helping to improve this mode.

2.1 Outlines
============

Org-mode is implemented on top of outline-mode.  Outlines allow to
organize a document in a hierarchical structure, which (at least for
me) is the best representation of notes and thoughts.  Overview over
this structure is achieved by folding (hiding) large parts of the
document to show only the general document structure and the parts
currently being worked on.  Org-mode greatly simplifies the use of
outlines by compressing the entire show/hide functionality into a
single command `org-cycle', which is bound to the <TAB> key.

\x1f
File: org,  Node: Headlines,  Next: Visibility cycling,  Prev: Outlines,  Up: Document structure

2.2 Headlines
=============

Headlines define the structure of an outline tree.  The headlines in
Org-mode start with one or more stars, on the left margin.  For example:

     * Top level headline
     ** Second level
     *** 3rd level
         some text
     *** 3rd level
         more text
     * Another top level headline

Some people find the many stars too noisy and would prefer an outline
that has whitespace followed by a single star as headline starters.
*Note Clean view:: describes a setup to realize this.

\x1f
File: org,  Node: Visibility cycling,  Next: Motion,  Prev: Headlines,  Up: Document structure

2.3 Visibility cycling
======================

Outlines make it possible to hide parts of the text in the buffer.
Org-mode uses just two commands, bound to <TAB> and `S-<TAB>' to change
the visibility in the buffer.

`<TAB>'
     _Subtree cycling_: Rotate current subtree between the states

          ,-> FOLDED -> CHILDREN -> SUBTREE --.
          '-----------------------------------'

     The cursor must be on a headline for this to work(1).  When the
     cursor is at the beginning of the buffer and the first line is not
     a headline, then <TAB> actually runs global cycling (see
     below)(2).  Also when called with a prefix argument (`C-u <TAB>'),
     global cycling is invoked.

`S-<TAB>'
`C-u <TAB>'
     _Global cycling_: Rotate the entire buffer between the states

          ,-> OVERVIEW -> CONTENTS -> SHOW ALL --.
          '--------------------------------------'

     Note that inside tables, `S-<TAB>' jumps to the previous field.

`C-c C-a'
     Show all.

   When Emacs first visits an Org-mode file, the global state is set to
OVERVIEW, i.e. only the top level headlines are visible.  This can be
configured through the variable `org-startup-folded', or on a per-file
basis by adding one of the following lines anywhere in the buffer:

     #+STARTUP: overview
     #+STARTUP: content
     #+STARTUP: showall

   ---------- Footnotes ----------

   (1) see, however, the option `org-cycle-emulate-tab'.

   (2) see the option `org-cycle-global-at-bob'.

\x1f
File: org,  Node: Motion,  Next: Structure editing,  Prev: Visibility cycling,  Up: Document structure

2.4 Motion
==========

The following commands jump to other headlines in the buffer.

`C-c C-n'
     Next heading.  

`C-c C-p'
     Previous heading.  

`C-c C-f'
     Next heading same level.  

`C-c C-b'
     Previous heading same level.  

`C-c C-u'
     Backward to higher level heading.  

`C-c C-j'
     Jump to a different place without changing the current outline
     visibility.  Shows the document structure in a temporary buffer,
     where you can use visibility cycling (<TAB>) to find your
     destination.  After pressing <RET>, the cursor moves to the
     selected location in the original buffer, and the headings
     hierarchy above it is made visible.

\x1f
File: org,  Node: Structure editing,  Next: Archiving,  Prev: Motion,  Up: Document structure

2.5 Structure editing
=====================

`M-<RET>'
     Insert new heading with same level as current.  If the cursor is
     in a plain list item, a new item is created (*note Plain lists::).
     To force creation of a new headline, use a prefix arg, or first
     press <RET> to get to the beginning of the next line.  When this
     command is used in the middle of a line, the line is split and the
     rest of the line becomes the new headline.  If the command is used
     at the beginning of a headline, the new headline is created before
     the current line.  If at the beginning of any other line, the
     content of that line is made the new heading.  

`M-S-<RET>'
     Insert new TODO entry with same level as current heading.  

`M-<left>'
     Promote current heading by one level.  

`M-<right>'
     Demote current heading by one level.  

`M-S-<left>'
     Promote the current subtree by one level.  

`M-S-<right>'
     Demote the current subtree by one level.  

`M-S-<up>'
     Move subtree up (swap with previous subtree of same level).  

`M-S-<down>'
     Move subtree down (swap with next subtree of same level).  

`C-c C-x C-w'
`C-c C-x C-k'
     Kill subtree, i.e. remove it from buffer but save in kill ring.  

`C-c C-x M-w'
     Copy subtree to kill ring.  

`C-c C-x C-y'
     Yank subtree from kill ring.  This does modify the level of the
     subtree to make sure the tree fits in nicely at the yank position.
     The yank level can also be specified with a prefix arg, or by
     yanking after a headline marker like `****'.

   When there is an active region (transient-mark-mode), promotion and
demotion work on all headlines in the region.  To select a region of
headlines, it is best to place both point and mark at the beginning of a
line, mark at the beginning of the first headline, and point at the line
just after the last headline to change.  Note that when the cursor is
inside a table (*note Tables::), the Meta-Cursor keys have different
functionality.

2.6 Archiving
=============

When a project represented by a (sub)tree is finished, you may want to
move the tree out of the way and to stop it from contributing to the
agenda.  Org-mode knows two ways of archiving.  You can mark a tree with
the ARCHIVE tag, or you can move an entire (sub)tree to a different
location.

* Menu:

* ARCHIVE tag::                 Marking a tree as inactive
* Moving subtrees::             Moving a tree to an archive file

\x1f
File: org,  Node: ARCHIVE tag,  Next: Moving subtrees,  Prev: Archiving,  Up: Archiving

2.6.1 The ARCHIVE tag
---------------------

A headline that is marked with the ARCHIVE tag (*note Tags::) stays at
its location in the outline tree, but behaves in the following way:
   - It does not open when you attempt to do so with a visibility
     cycling command (*note Visibility cycling::).  You can still open
     it with a normal outline command like `show-all'.  Or you can
     modify the option `org-cycle-open-archived-trees'.

   - During sparse tree construction (*note Sparse trees::), matches in
     archived subtrees are not exposed, unless you configure the option
     `org-sparse-tree-open-archived-trees'.

   - During agenda view construction (*note Agenda views::), the
     content of archived trees is ignored unless you configure the
     option `org-agenda-skip-archived-trees'.

   - Archived trees are not exported (*note Exporting::), only the
     headline is.  Configure the details using the variable
     `org-export-with-archived-trees'.

   The following commands allow to set or clear the ARCHIVE tag:

`C-c C-x C-a'
     Toggle the ARCHIVE tag for the current headline.  When the tag is
     set, the headline changes to a shadowish face, and the subtree
     below it is hidden.  

`C-u C-c C-x C-a'
     Check if any direct children of the current headline should be
     archived.  To do this, each subtree is checked for open TODO
     entries.  If none are found, the command offers to set the ARCHIVE
     tag for the child.  If the cursor is _not_ on a headline when this
     command is invoked, the level 1 trees will be checked.

\x1f
File: org,  Node: Moving subtrees,  Prev: ARCHIVE tag,  Up: Archiving

2.6.2 Moving subtrees
---------------------

Once an entire project is finished, you may want to move it to a
different location, either in the current file, or even in a different
file, the archive file.

`C-c $'
     Archive the subtree starting at the cursor position to the location
     given by `org-archive-location'.  

`C-u C-c $'
     Check if any direct children of the current headline could be
     moved to the archive.  To do this, each subtree is checked for
     open TODO entries.  If none are found, the command offers to move
     it to the archive location.  If the cursor is _not_ on a headline
     when this command is invoked, the level 1 trees will be checked.

   The default archive location is a file in the same directory as the
current file, with the name derived by appending `_archive' to the
current file name.  For information and examples on how to change this,
see the documentation string of the variable `org-archive-location'.

2.7 Sparse trees
================

An important feature of Org-mode is the ability to construct _sparse
trees_ for selected information in an outline tree.  A sparse tree
means that the entire document is folded as much as possible, but the
selected information is made visible along with the headline structure
above it(1).  Just try it out and you will see immediately how it works.

   Org-mode contains several commands creating such trees.  The most
basic one is `org-occur':

`C-c /'
     Occur.  Prompts for a regexp and shows a sparse tree with all
     matches.  If the match is in a headline, the headline is made
     visible.  If the match is in the body of an entry, headline and
     body are made visible.  In order to provide minimal context, also
     the full hierarchy of headlines above the match is shown, as well
     as the headline following the match.  Each match is also
     highlighted; the highlights disappear when the buffer is changed
     with an editing command.
   For frequently used sparse trees of specific search strings, you can
use the variable `org-agenda-custom-commands' to define fast keyboard
access to specific sparse trees.  These commands will then be
accessible through the agenda dispatcher (*note Agenda dispatcher::).
For example:

     (setq org-agenda-custom-commands
           '(("f" occur-tree "FIXME")))

will define the key `C-c a f' as a shortcut for creating a sparse tree
matching the string `FIXME'.

   Other commands use sparse trees as well.  For example `C-c C-v'
creates a sparse TODO tree (*note TODO basics::).

   To print a sparse tree, you can use the Emacs command
`ps-print-buffer-with-faces' which does not print invisible parts of
the document (2).  Or you can use the command `C-c C-x v' to export
only the visible part of the document and print the resulting file.

   ---------- Footnotes ----------

   (1) See also the variables `org-show-hierarchy-above' and
`org-show-following-heading'.

   (2) This does not work under XEmacs, because XEmacs uses selective
display for outlining, not text properties.

2.8 Plain lists
===============

Headlines define both the structure of the Org-mode file, and also lists
(for example, TODO items (*note TODO items::) should be created using
headline levels).  When taking notes, however, the plain text is
sometimes easier to read with hand-formatted lists.  Org-mode supports
editing such lists, and the HTML exporter (*note Exporting::) does
parse and format them.

   Org-mode knows ordered and unordered lists.  Unordered list items
start with `-', `+', or `*'(1) as bullets.  Ordered list items start
with `1.' or `1)'.  Items belonging to the same list must have the same
indentation on the first line.  In particular, if an ordered list
reaches number `10.', then the 2-digit numbers must be written
left-aligned with the other numbers in the list.  Indentation also
determines the end of a list item.  It ends before the next line that
is indented like the bullet/number, or less.  For example:

     ** Lord of the Rings
     My favorite scenes are (in this order)
     1. Eowyns fight with the witch king
        + this was already my favorite scene in the book
        + I really like Miranda Otto.
     2. The attack of the Rohirrim
     3. Peter Jackson being shot by Legolas
         - on DVD only
        He makes a really funny face when it happens.
     But in the end, not individual scenes matter but the film as a whole.

   Org-mode supports these lists by tuning filling and wrapping commands
to deal with them correctly.

   The following commands act on items when the cursor is in the first
line of an item (the line with the bullet or number).

`<TAB>'
     Items can be folded just like headline levels if you set the
     variable `org-cycle-include-plain-lists'.  The level of an item is
     then given by the indentation of the bullet/number.  Items are
     always subordinate to real headlines, however; the hierarchies
     remain completely separated.  

`M-<RET>'
     Insert new item at current level.  With prefix arg, force a new
     heading (*note Structure editing::).  If this command is used in
     the middle of a line, the line is _split_ and the rest of the line
     becomes the new item.  If this command is executed in the
     _whitespace before a bullet or number_, the new item is created
     _before_ the current item.  If the command is executed in the
     white space before the text that is part of an item but does not
     contain the bullet, a bullet is added to the current line.  

`M-S-<RET>'
     Insert a new item with a checkbox (*note Checkboxes::).  

`S-<up>'
`S-<down>'
     Jump to the previous/next item in the current list.  

`M-S-<up>'
`M-S-<down>'
     Move the item including subitems up/down (swap with previous/next
     item of same indentation).  If the list is ordered, renumbering is
     automatic.  

`M-S-<left>'
`M-S-<right>'
     Decrease/increase the indentation of the item, including subitems.
     Initially, the item tree is selected based on current indentation.
     When these commands are executed several times in direct
     succession, the initially selected region is used, even if the new
     indentation would imply a different hierarchy.  To use the new
     hierarchy, break the command chain with a cursor motion or so.  

`C-c C-c'
     If there is a checkbox (*note Checkboxes::) in the item line,
     toggle the state of the checkbox.  Otherwise, if this is an
     ordered list, renumber the ordered list at the cursor.

   ---------- Footnotes ----------

   (1) When using `*' as a bullet, lines must be indented or they will
be seen as top-level headlines.  Also, when you are hiding leading
stars to get a clean outline view, plain list items starting with a
star are visually indistinguishable from true headlines.  In short:
even though `*' is supported, it may be better not to use it for plain
list items

\x1f
File: org,  Node: Checkboxes,  Prev: Plain lists,  Up: Document structure

2.9 Checkboxes
==============

Every item in a plain list (ordered and unordered) can be made a
checkbox by starting it with the string `[ ]'.  This feature is similar
to TODO items (*note TODO items::), but more lightweight.  Checkboxes
are not included into the global TODO list, so they are often great to
split a task into a number of simple steps.  Or you can use them in a
shopping list to select the items you need to buy.  To toggle a
checkbox, use `C-c C-c', or try Piotr Zielinski's `org-mouse.el'.  Here
is an example of a checkbox list.

     * Avoid stupid mistakes when distributing a new version
       - [ ] update also Emacs CVS
       - [X] forget to update index.html on the website
       - [X] leaving a `(debug)' form in the code

The following commands work with checkboxes:

`C-c C-c'
     Toggle checkbox at point.  

`C-c C-x C-b'
     Toggle checkbox at point.
        - If there is an active region, toggle the first checkbox in
          the region and set all remaining boxes to the same status as
          the first.  If you want to toggle all boxes in the region
          independently, use a prefix argument.

        - If the cursor is in a headline, toggle checkboxes in the
          region between this headline and the next.  This does _not_
          act on the entire subtree, just the current entry.

        - If no active region, just toggle the checkbox at point.
     
`M-S-<RET>'
     Insert a new item with a checkbox.  This works only if the cursor
     is already in a plain list item (*note Plain lists::).

3.1 The built-in table editor
=============================

Org-mode makes it easy to format tables in plain ASCII.  Any line with
`|' as the first non-white character is considered part of a table.
`|' is also the column separator.  A table might look like this:

     | Name  | Phone | Age |
     |-------+-------+-----|
     | Peter |  1234 |  17 |
     | Anna  |  4321 |  25 |

   A table is re-aligned automatically each time you press <TAB> or
<RET> or `C-c C-c' inside the table.  <TAB> also moves to the next
field (<RET> to the next row) and creates new table rows at the end of
the table or before horizontal lines.  The indentation of the table is
set by the first line.  Any line starting with `|-' is considered as a
horizontal separator line and will be expanded on the next re-align to
span the whole table width.  So, to create the above table, you would
only type

     |Name|Phone|Age
     |-

and then press <TAB> to align the table and start filling in fields.

   When typing text into a field, Org-mode treats <DEL>, <Backspace>,
and all character keys in a special way, so that inserting and deleting
avoids shifting other fields.  Also, when typing _immediately after the
cursor was moved into a new field with `<TAB>', `S-<TAB>' or `<RET>'_,
the field is automatically made blank.  If this behavior is too
unpredictable for you, configure the variables
`org-enable-table-editor' and `org-table-auto-blank-field'.

Creation and conversion
.......................

`C-c |'
     Convert the active region to table. If every line contains at
     least one TAB character, the function assumes that the material is
     tab separated.  If not, lines are split at whitespace into fields.
     You can use a prefix argument to indicate the minimum number of
     consecutive spaces required to identify a field separator
     (default: just one).
     If there is no active region, this command creates an empty
     Org-mode table.  But it's easier just to start typing, like
     `|Name|Phone|Age <RET> |- <TAB>'.

Re-aligning and field motion
............................

`C-c C-c'
     Re-align the table without moving the cursor.

`<TAB>'
     Re-align the table, move to the next field.  Creates a new row if
     necessary.

`S-<TAB>'
     Re-align, move to previous field.

`<RET>'
     Re-align the table and move down to next row.  Creates a new row if
     necessary.  At the beginning or end of a line, <RET> still does
     NEWLINE, so it can be used to split a table.

Column and row editing
......................

`M-<left>'
`M-<right>'
     Move the current column left/right.

`M-S-<left>'
     Kill the current column.

`M-S-<right>'
     Insert a new column to the left of the cursor position.

`M-<up>'
`M-<down>'
     Move the current row up/down.

`M-S-<up>'
     Kill the current row or horizontal line.

`M-S-<down>'
     Insert a new row above (with arg: below) the current row.

`C-c -'
     Insert a horizontal line below current row. With prefix arg, the
     line is created above the current line.

`C-c ^'
     Sort the table lines in the region.  Point and mark must be in the
     first and last line to be included, and must be in the column that
     should be used for sorting.  The command prompts for numerical
     versus alphanumerical sorting.

Regions
.......

`C-c C-x M-w'
     Copy a rectangular region from a table to a special clipboard.
     Point and mark determine edge fields of the rectangle.  The
     process ignores horizontal separator lines.  

`C-c C-x C-w'
     Copy a rectangular region from a table to a special clipboard, and
     blank all fields in the rectangle.  So this is the "cut" operation.  

`C-c C-x C-y'
     Paste a rectangular region into a table.  The upper right corner
     ends up in the current field.  All involved fields will be
     overwritten.  If the rectangle does not fit into the present table,
     the table is enlarged as needed.  The process ignores horizontal
     separator lines.  

`C-c C-q'
     Wrap several fields in a column like a paragraph.  If there is an
     active region, and both point and mark are in the same column, the
     text in the column is wrapped to minimum width for the given
     number of lines.  A prefix ARG may be used to change the number of
     desired lines.  If there is no region, the current field is split
     at the cursor position and the text fragment to the right of the
     cursor is prepended to the field one line down. If there is no
     region, but you specify a prefix ARG, the current field is made
     blank, and the content is appended to the field above.

Calculations
............

`C-c ='
     Install a new formula for the current column and replace current
     field with the result of the formula.

`C-u C-c ='
     Install a new formula for the current field, which must be a named
     field.  Evaluate the formula and replace the field content with the
     result.

`C-c ''
     Edit all formulas associated with the current table in a separate
     buffer.

`C-c *'
     Recalculate the current row by applying the stored formulas from
     left to right.  When called with a `C-u' prefix, recalculate the
     entire table, starting with the first non-header line (i.e. below
     the first horizontal separator line).  For details, see *Note
     Table calculations::.

`C-#'
     Rotate the calculation mark in first column through the states `',
     `#', `*', `!', `$'.  For the meaning of these marks see *Note
     Advanced features::.  When there is an active region, change all
     marks in the region.

`C-c ?'
     Which table column is the cursor in?  Displays number >0 in echo
     area.

`C-c +'
     Sum the numbers in the current column, or in the rectangle defined
     by the active region.  The result is shown in the echo area and can
     be inserted with `C-y'.

`S-<RET>'
     When current field is empty, copy from first non-empty field above.
     When not empty, copy current field down to next row and move cursor
     along with it.  Depending on the variable
     `org-table-copy-increment', integer field values will be
     incremented during copy.  This key is also used by CUA-mode (*note
     Cooperation::).

Miscellaneous
.............

`C-c `'
     Edit the current field in a separate window.  This is useful for
     fields that are not fully visible (*note Narrow columns::).  When
     called with a `C-u' prefix, just make the full field visible, so
     that it can be edited in place.

`C-c <TAB>'
     This is an alias for `C-u C-c `' to make the current field fully
     visible.

`M-x org-table-import'
     Import a file as a table.  The table should be TAB- or whitespace
     separated.  Useful, for example, to import an Excel table or data
     from a database, because these programs generally can write
     TAB-separated text files.  This command works by inserting the
     file into the buffer and then converting the region to a table.
     Any prefix argument is passed on to the converter, which uses it
     to determine the separator.

`M-x org-table-export'
     Export the table as a TAB-separated file.  Useful for data
     exchange with, for example, Excel or database programs.


   If you don't like the automatic table editor because it gets in your
way on lines which you would like to start with `|', you can turn it
off with

     (setq org-enable-table-editor nil)

Then the only table command that still works is `C-c C-c' to do a
manual re-align.

\x1f
File: org,  Node: Narrow columns,  Next: Table calculations,  Prev: Built-in table editor,  Up: Tables

3.2 Narrow columns
==================

The width of columns is automatically determined by the table editor.
Sometimes a single field or a few fields need to carry more text,
leading to inconveniently wide columns.  To limit(1) the width of a
column, one field anywhere in the column may contain just the string
`<N>' where `N' is an integer specifying the width of the column in
characters.  The next re-align will then set the width of this column
to no more than this value.

     |---+------------------------------|               |---+--------|
     |   |                              |               |   | <6>    |
     | 1 | one                          |               | 1 | one    |
     | 2 | two                          |     ----\     | 2 | two    |
     | 3 | This is a long chunk of text |     ----/     | 3 | This=> |
     | 4 | four                         |               | 4 | four   |
     |---+------------------------------|               |---+--------|

Fields that are wider become clipped and end in the string `=>'.  Note
that the full text is still in the buffer, it is only invisible.  To
see the full text, hold the mouse over the field - a tooltip window
will show the full content.  To edit such a field, use the command `C-c
`' (that is `C-c' followed by the backquote).  This will open a new
window with the full field.  Edit it and finish with `C-c C-c'.

   When visiting a file containing a table with narrowed columns, the
necessary character hiding has not yet happened, and the table needs to
be aligned before it looks nice.  Setting the option
`org-startup-align-all-tables' will realign all tables in a file upon
visiting, but also slow down startup.  You can also set this option on
a per-file basis with:

     #+STARTUP: align
     #+STARTUP: noalign

3.3 Calculations in tables
==========================

The table editor makes use of the Emacs `calc' package to implement
spreadsheet-like capabilities.  It can also evaluate Emacs Lisp forms to
derive fields from other fields.  Org-mode has two levels of complexity
for table calculations.  On the basic level, tables do only horizontal
computations, so a field can be computed from other fields _in the same
row_, and Org-mode assumes that there is only one formula for each
column.  This is very efficient to work with and enough for many tasks.
On the complex level, columns and individual fields can be named for
easier referencing in formulas, individual named fields can have their
own formula associated with them, and recalculation can be automated.

\x1f
File: org,  Node: Formula syntax,  Next: Lisp formulas,  Prev: Table calculations,  Up: Table calculations

3.3.1 Formula syntax
--------------------

A formula can be any algebraic expression understood by the Emacs
`calc' package.  Note that `calc' has the slightly non-standard
convention that `/' has lower precedence than `*', so that `a/b*c' is
interpreted as `a/(b*c)'.  Before evaluation by `calc-eval' (*note
calc-eval: (calc)Calling Calc from Your Programs.), variable
substitution takes place:

       $        refers to the current field
       $3       refers to the field in column 3 of the current row
       $3..$7   a vector of the fields in columns 3-7 of current row
       $P1..$P3 vector of column range, using column names
       &2       second data field above the current, in same column
       &5-2     vector from fifth to second field above current
       &III-II  vector of fields between 2nd and 3rd hline above
       &III     vector of fields between third hline above and current field
       $name    a named field, parameter or constant

   The range vectors can be directly fed into the calc vector functions
like `vmean' and `vsum'.

   `$name' is interpreted as the name of a column, parameter or
constant.  Constants are defined globally through the variable
`org-table-formula-constants'.  If you have the `constants.el' package,
it will also be used to resolve constants, including natural constants
like `$h' for Planck's constant, and units like `$km' for kilometers.
Column names and parameters can be specified in special table lines.
These are described below, see *Note Advanced features::.

   A formula can contain an optional mode string after a semicolon.
This string consists of flags to influence calc's modes(1) during
execution, e.g.  `p20' to switch the internal precision to 20 digits,
`n3', `s3', `e2' or `f4' to switch to normal, scientific, engineering,
or fixed display format, respectively, and `D', `R', `F', and `S' to
turn on degrees, radians, fraction and symbolic modes, respectively.
In addition, you may provide a `printf' format specifier to reformat
the final result.  A few examples:

     $1+$2                Sum of first and second field
     $1+$2;%.2f           Same, format result to two decimals
     exp($2)+exp($1)      Math functions can be used
     $;%.1f               Reformat current cell to 1 decimal
     ($3-32)*5/9          Degrees F -> C conversion
     $c/$1/$cm            Hz -> cm conversion, using `constants.el'
     tan($1);Dp3s1        Compute in degrees, precision 3, display SCI 1
     sin($1);Dp3%.1e      Same, but use printf specifier for display
     vmean($2..$7)        Compute column range mean, using vector function
     vsum(&III)           Sum numbers from 3rd hline above, up to here
     taylor($3,x=7,2)     taylor series of $3, at x=7, second degree

   ---------- Footnotes ----------

   (1) By default, Org-mode uses the standard calc modes (precision 12,
angular units degrees, fraction and symbolic modes off).  The display
format, however, has been changed to `(float 5)' to keep tables compact.
The default settings can be configured using the variable
`org-calc-default-modes'.

3.3.2 Emacs Lisp forms as formulas
----------------------------------

It is also possible to write a formula in Emacs lisp; this can be useful
for string manipulation and control structures.  If a formula starts
with a single quote followed by an opening parenthesis, then it is
evaluated as a lisp form.  The evaluation should return either a string
or a number.  Just as with `calc' formulas, you can provide a format
specifier after a semicolon.  A few examples:

     swap the first two characters of the content of column 1
     '(concat (substring "$1" 1 2) (substring "$1" 0 1) (substring "$1" 2))
     Add columns 1 and 2, equivalent to the calc's `$1+$2'
     '(+ $1 $2)

\x1f
File: org,  Node: Column formulas,  Next: Advanced features,  Prev: Lisp formulas,  Up: Table calculations

3.3.3 Column formulas
---------------------

To apply a formula to a field, type it directly into the field,
preceded by an equal sign, like `=$1+$2'.  When you press <TAB> or
<RET> or `C-c C-c' with the cursor still in the field, the formula will
be stored as the formula for the current column, evaluated and the
current field replaced with the result.  If the field contains only
`=', the previously stored formula for this column is used.

   For each column, Org-mode will remember the most recently used
formula.  The information is stored in a special line starting with
`#+TBLFM' directly below the table.  When adding/deleting/moving
columns with the appropriate commands, the stored equations will be
modified accordingly.  When a column used in a calculation is removed,
references to this column become invalid and will cause an error upon
applying the equation.

   Instead of typing an equation into the field, you may also use the
command `C-c ='.  It prompts for a formula (with default taken from the
`#+TBLFM:' line) and applies it to the current field.  A numerical
prefix (e.g. `C-5 C-c =') will apply it to that many consecutive fields
in the current column.

   To recompute all the fields in a line, use the command `C-c *'.  It
re-applies all stored equations to the current row, from left to right.
With a `C-u' prefix, this will be done to every line in the table, so
use this command it you want to make sure the entire table is
up-to-date. `C-u C-c C-c' is another way to update the entire table.
Global updating does not touch the line(s) above the first horizontal
separator line, assuming that this is the table header.

3.3.4 Advanced features
-----------------------

If you want the recalculation of fields to happen automatically, or if
you want to be able to assign a formula to an individual field (instead
of an entire column) you need to reserve the first column of the table
for special marking characters.  Here is an example of a table that
collects exam results of students and makes use of these features:

     |---+---------+--------+--------+--------+-------+------|
     |   | Student | Prob 1 | Prob 2 | Prob 3 | Total | Note |
     |---+---------+--------+--------+--------+-------+------|
     | ! |         |     P1 |     P2 |     P3 |   Tot |      |
     | # | Maximum |     10 |     15 |     25 |    50 | 10.0 |
     | ^ |         |     m1 |     m2 |     m3 |    mt |      |
     |---+---------+--------+--------+--------+-------+------|
     | # | Peter   |     10 |      8 |     23 |    41 |  8.2 |
     | # | Sara    |      6 |     14 |     19 |    39 |  7.8 |
     | # | Sam     |      2 |      4 |      3 |     9 |  1.8 |
     |---+---------+--------+--------+--------+-------+------|
     |   | Average |        |        |        |  29.7 |      |
     | ^ |         |        |        |        |    at |      |
     | $ | max=50  |        |        |        |       |      |
     |---+---------+--------+--------+--------+-------+------|
     #+TBLFM: $6=vsum($P1..$P3)::$7=10*$Tot/$max;%.1f::$at=vmean(&II);%.1f

Important: Please note that for these special tables, recalculating the
table with `C-u C-c *' will only affect rows that are marked `#' or
`*', and named fields.  The column formulas are not applied in rows
with empty first field.

   The marking characters have the following meaning:
`!'
     The fields in this line define names for the columns, so that you
     may refer to a column as `$Tot' instead of `$6'.

`^'
     This row defines names for the fields _above_ the row.  With such
     a definition, any formula in the table may use `$m1' to refer to
     the value `10'.  Also, named fields can have their own formula
     associated with them.

`_'
     Similar to `^', but defines names for the fields in the row
     _below_.

`$'
     Fields in this row can define _parameters_ for formulas.  For
     example, if a field in a `$' row contains `max=50', then formulas
     in this table can refer to the value 50 using `$max'.  Parameters
     work exactly like constants, only that they can be defined on a
     per-table basis.  Changing a parameter and then recalculating the
     table can be useful.

`#'
     Fields in this row are automatically recalculated when pressing
     <TAB> or <RET> or `S-<TAB>' in this row.  Also, this row is
     selected for a global recalculation with `C-u C-c *'.  Unmarked
     lines will be left alone by this command.

`*'
     Selects this line for global recalculation with `C-u C-c *', but
     not for automatic recalculation.  Use this when automatic
     recalculation slows down editing too much.

`'
     Unmarked lines are exempt from recalculation with `C-u C-c *'.
     All lines that should be recalculated should be marked with `#' or
     `*'.

File: org,  Node: Named-field formulas,  Next: Editing/debugging formulas,  Prev: Advanced features,  Up: Table calculations

3.3.5 Named-field formulas
--------------------------

A named field can have its own formula associated with it.  In the
example above, this is used for the `at' field that contains the
average result of the students.  To enter a formula for a named field,
just type it into the buffer, preceded by `:='.  Or use `C-u C-c ='.
This equation will be stored below the table like `$name=...'.  Any
recalculation in the table (even if only requested for the current
line) will also update all named field formulas.

\x1f
File: org,  Node: Editing/debugging formulas,  Next: Appetizer,  Prev: Named-field formulas,  Up: Table calculations

3.3.6 Editing and debugging formulas
------------------------------------

To edit a column or field formula, use the commands `C-c =' and `C-u
C-c =', respectively.  The currently active expression is then
presented as default in the minibuffer, where it may be edited.

   Note that making a table field blank does not remove the formula
associated with the field - during the next recalculation the field
will be filled again.  To remove a formula from a field, you have to
give an empty reply when prompted for the formula, or to edit the
`#+TBLFM' line.

   You may edit the `#+TBLFM' directly and re-apply the changed
equations with `C-c C-c' in that line, or with the normal recalculation
commands in the table.

   In particular for large tables with many formulas, it is convenient
to use the command `C-c '' to edit the formulas of the current table in
a separate buffer.  That buffer will show the formulas one per line,
and you are free to edit, add and remove formulas.  Press `C-c ?' on a
`$...'  expression to get information about its interpretation.
Exiting the buffer with `C-c C-c' only stores the modified formulas
below the table.  Exiting with `C-u C-c C-c' also applies them to the
entire table.  `C-c C-q' exits without installing the changes.

   When the evaluation of a formula leads to an error, the field content
becomes the string `#ERROR'.  If you would like see what is going on
during variable substitution and calculation in order to find a bug,
turn on formula debugging in the menu and repeat the calculation, for
example by pressing `C-c = <RET>' in a field.  Detailed information
will be displayed.

3.4 The Orgtbl minor mode
=========================

If you like the intuitive way the Org-mode table editor works, you
might also want to use it in other modes like text-mode or mail-mode.
The minor mode Orgtbl-mode makes this possible.  You can always toggle
the mode with `M-x orgtbl-mode'.  To turn it on by default, for example
in mail mode, use

     (add-hook 'mail-mode-hook 'turn-on-orgtbl)

File: org,  Node: table.el,  Prev: orgtbl-mode,  Up: Tables

3.5 The `table.el' package
==========================

Complex ASCII tables with automatic line wrapping, column- and
row-spanning, and alignment can be created using the Emacs table
package by Takaaki Ota (`http://sourceforge.net/projects/table', and
also part of Emacs 22).  When <TAB> or `C-c C-c' is pressed in such a
table, Org-mode will call `table-recognize-table' and move the cursor
into the table.  Inside a table, the keymap of Org-mode is inactive.
In order to execute Org-mode-related commands, leave the table.

`C-c C-c'
     Recognize `table.el' table.  Works when the cursor is in a
     table.el table.

`C-c ~'
     Insert a table.el table.  If there is already a table at point,
     this command converts it between the table.el format and the
     Org-mode format.  See the documentation string of the command
     `org-convert-table' for the restrictions under which this is
     possible.

\x1f
File: org,  Node: Link format,  Next: Internal links,  Prev: Hyperlinks,  Up: Hyperlinks

4.1 Link format
===============

Org-mode will recognize plain URL-like links and activate them as
clickable links.  The general link format, however, looks like this:

     [[link][description]]       or alternatively           [[link]]

   Once a link in the buffer is complete (all brackets present),
Org-mode will change the display so that `description' is displayed
instead of `[[link][description]]' and `link' is displayed instead of
`[[link]]'.  Links will be highlighted in the face `org-link', which by
default is an underlined face.  You can directly edit the visible part
of a link.  Note that this can be either the `link' part (if there is
no description) or the `description' part.  To edit also the invisible
`link' part, use `C-c C-l' with the cursor on the link.

   If you place the cursor at the beginning or just behind the end of
the displayed text and press <BACKSPACE>, you will remove the
(invisible) bracket at that location.  This makes the link incomplete
and the internals are again displayed as plain text.  Inserting the
missing bracket hides the link internals again.  To show the internal
structure of all links, use the menu entry `Org->Hyperlinks->Literal
links'.

\x1f
File: org,  Node: Internal links,  Next: External links,  Prev: Link format,  Up: Hyperlinks

4.2 Internal links
==================

If the link does not look like a URL, it is considered to be internal in
the current file.  Links such as `[[My Target]]' or `[[My Target][Find
my target]]' lead to a text search in the current file.  The link can
be followed with `C-c C-o' when the cursor is on the link, or with a
mouse click (*note Handling links::).  The preferred match for such a
link is a dedicated target: the same string in double angular brackets.
Targets may be located anywhere; often it is convenient to put them
into a comment line. For example

     # <<My Target>>

In HTML export (*note HTML export::), such targets will become named
anchors for direct access through `http' links(1).

   If no dedicated target exists, Org-mode will search for the words in
the link.  In the above example the search would be for `my target'.
Links starting with a star like `*My Target' restrict the search to
headlines.  When searching, Org-mode will first try an exact match, but
then move on to more and more lenient searches.  For example, the link
`[[*My Targets]]' will find any of the following:

     ** My targets
     ** TODO my targets are bright
     ** my 20 targets are

   To insert a link targeting a headline, in-buffer completion can be
used.  Just type a star followed by a few optional letters into the
buffer and press `M-<TAB>'.  All headlines in the current buffer will be
offered as completions.  *Note Handling links::, for more commands
creating links.

   Following a link pushes a mark onto Org-mode's own mark ring.  You
can return to the previous position with `C-c &'.  Using this command
several times in direct succession goes back to positions recorded
earlier.

* Menu:

* Radio targets::               Make targets trigger links in plain text.
* CamelCase links::             Activating CamelCase words as links

   ---------- Footnotes ----------

   (1) Note that text before the first headline will never be exported,
so the first such target must be after the first headline.

File: org,  Node: Radio targets,  Next: CamelCase links,  Prev: Internal links,  Up: Internal links

4.2.1 Radio targets
-------------------

You can configure Org-mode to link any occurrences of certain target
names in normal text.  So without explicitly creating a link, the text
connects to the target radioing its position.  Radio targets are
enclosed by triple angular brackets.  For example, a target `<<<My
Target>>>' causes each occurrence of `my target' in normal text to
become activated as a link.  The Org-mode file is scanned automatically
for radio targets only when the file is first loaded into Emacs.  To
update the target list during editing, press `C-c C-c' with the cursor
on or at a target.

\x1f
File: org,  Node: CamelCase links,  Prev: Radio targets,  Up: Internal links

4.2.2 CamelCase words as links
------------------------------

Org-mode also supports CamelCase words as links.  This feature is not
turned on by default because of the inconsistencies this system suffers
from.  To activate CamelCase words as links, you need to customize the
option `org-activate-links'.  A CamelCase word then leads to a text
search such that `CamelCaseLink' is equivalent to `[[camel case link]]'.

File: org,  Node: External links,  Next: Handling links,  Prev: Internal links,  Up: Hyperlinks

4.3 External links
==================

Org-mode supports links to files, websites, Usenet and email messages,
and BBDB database entries.  External links are URL-like locators.  They
start with a short identifying string followed by a colon.  There can be
no space after the colon.  The following list shows examples for each
link type.

   A link should be enclosed in double brackets and may contain a
descriptive text to be displayed instead of the url (*note Link
format::), for example:

     [[http://www.gnu.org/software/emacs/][GNU Emacs]]

   Org-mode also finds external links in the normal text and activates
them as links.  If spaces must be part of the link (for example in
`bbdb:Richard Stallman'), or you need to remove ambiguities about the
end of the link, enclose them in angular brackets.

\x1f
File: org,  Node: Handling links,  Next: Search options,  Prev: External links,  Up: Hyperlinks

4.4 Handling links
==================

Org-mode provides methods to create a link in the correct syntax, to
insert it into an org-mode file, and to follow the link.

`C-c l'
     Store a link to the current location.  This is a _global_ command
     which can be used in any buffer to create a link.  The link will be
     stored for later insertion into an Org-mode buffer (see below).
     For Org-mode files, if there is a `<<target>>' at the cursor, the
     link points to the target.  Otherwise it points to the current
     headline.  For VM, RMAIL, WANDERLUST, MH-E, GNUS and BBDB buffers,
     the link will indicate the current article/entry.  For W3 and W3M
     buffers, the link goes to the current URL.  For any other files,
     the link will point to the file, with a search string (*note
     Search options::) pointing to the contents of the current line.
     If there is an active region, the selected words will form the
     basis of the search string.  If the automatically created link is
     not working correctly or accurately enough, you can write custom
     functions to select the search string and to do the search for
     particular file types - see *Note Custom searches::.  The key
     binding `C-c l' is only a suggestion - see *Note Installation::.

`C-c C-l'
     Insert a link.  This prompts for a link to be inserted into the
     buffer.  You can just type a link, using text for an internal
     link, or one of the link type prefixes mentioned in the examples
     above.  Through completion, all links stored during the current
     session can be accessed(1).  The link will be inserted into the
     buffer, along with a descriptive text.  Note that you don't have
     to use this command to insert a link.  Links in Org-mode are plain
     text, and you can type or paste them straight into the buffer.  By
     using this command, the links are automatically enclosed in double
     brackets, and you will be asked for the optional descriptive text.
     If the link is a `file:' link and the linked file is located in
     the same directory as the current file or a subdirectory of it, the
     path of the file will be inserted relative to the current
     directory.

`C-u C-c C-l'
     When `C-c C-l' is called with a `C-u' prefix argument, a link to a
     file will be inserted and you may use file name completion to
     select the name of the file.  The path to the file is inserted
     relative to the directory of the current org file, if the linked
     file is in the current directory or in a subdirectory of it, or if
     the path is written relative to the current directory using `../'.
     Otherwise an absolute path is used, if possible with `~/' for
     your home directory.  You can force an absolute path with two
     `C-u' prefixes.

`C-c C-l with cursor on existing link'
     When the cursor is on an existing link, `C-c C-l' allows you to
     edit the link and description parts of the link.

`C-c C-o'
     Open link at point.  This will launch a web browser for URLs (using
     `browse-url-at-point'), run vm/mh-e/wanderlust/rmail/gnus/bbdb for
     the corresponding links, and execute the command in a shell link.
     When the cursor is on an internal link, this commands runs the
     corresponding search.  When the cursor is on a TAG list in a
     headline, it creates the corresponding TAGS view.  If the cursor
     is on a time stamp, it compiles the agenda for that date.
     Furthermore, it will visit text and remote files in `file:' links
     with Emacs and select a suitable application for local non-text
     files.  Classification of files is based on file extension only.
     See option `org-file-apps'.  If you want to override the default
     application and visit the file with Emacs, use a `C-u' prefix.

`mouse-2'
`mouse-1'
     On links, `mouse-2' will open the link just as `C-c C-o' would.
     Under Emacs 22, also `mouse-1' will follow a link.

`mouse-3'
     Like `mouse-2', but force file links to be opened with Emacs.

`C-c %'
     Push the current position onto the mark ring, to be able to return
     easily. Commands following an internal link do this automatically.

`C-c &'
     Jump back to a recorded position.  A position is recorded by the
     commands following internal links, and by `C-c %'.  Using this
     command several times in direct succession moves through a ring of
     previously recorded positions.

   ---------- Footnotes ----------

   (1) After insertion of a stored link, the link will be removed from
the list of stored links.  To keep it in the list later use, use a
triple `C-u' prefix to `C-c C-l', or configure the option
`org-keep-stored-link-after-insertion'.

\x1f
File: org,  Node: Search options,  Next: Custom searches,  Prev: Handling links,  Up: Hyperlinks

4.5 Search options in file links
================================

File links can contain additional information to make Emacs jump to a
particular location in the file when following a link.  This can be a
line number or a search option after a double(1) colon. For example,
when the command `C-c l' creates a link (*note Handling links::) to a
file, it encodes the words in the current line as a search string that
can be used to find this line back later when following the link with
`C-c C-o'.

   Here is the syntax of the different ways to attach a search to a file
link, together with an explanation:

     [[file:~/code/main.c::255]]
     [[file:~/xx.org::My Target]]
     [[file:~/xx.org::*My Target]]
     [[file:~/xx.org::/regexp/]]

`255'
     Jump to line 255.

`My Target'
     Search for a link target `<<My Target>>', or do a text search for
     `my target', similar to the search in internal links, see *Note
     Internal links::.  In HTML export (*note HTML export::), such a
     file link will become an HTML reference to the corresponding named
     anchor in the linked file.

`*My Target'
     In an Org-mode file, restrict search to headlines.

`/regexp/'
     Do a regular expression search for `regexp'.  This uses the Emacs
     command `occur' to list all matches in a separate window.  If the
     target file is in Org-mode, `org-occur' is used to create a sparse
     tree with the matches.

   As a degenerate case, a file link with an empty file name can be used
to search the current file.  For example, `<file:::find me>' does a
search for `find me' in the current file, just as `[[find me]]' would.

   ---------- Footnotes ----------

   (1) For backward compatibility, line numbers can also follow a
single colon.

File: org,  Node: Custom searches,  Next: Remember,  Prev: Search options,  Up: Hyperlinks

4.6 Custom Searches
===================

The default mechanism for creating search strings and for doing the
actual search related to a file link may not work correctly in all
cases.  For example, BibTeX database files have many entries like
`year="1993"' which would not result in good search strings, because
the only unique identification for a BibTeX entry is the citation key.

   If you come across such a problem, you can write custom functions to
set the right search string for a particular file type, and to do the
search for the string in the file.  Using `add-hook', these functions
need to be added to the hook variables
`org-create-file-search-functions' and
`org-execute-file-search-functions'.  See the docstring for these
variables for more information.  Org-mode actually uses this mechanism
for BibTeX database files, and you can use the corresponding code as an
implementation example.  Search for `BibTeX links' in the source file.

4.7 Remember
============

Another way to create org entries with links to other files is through
the _Remember_ package by John Wiegley.  _Remember_ lets you store
quick notes with little interruption of your work flow.  See
`http://www.emacswiki.org/cgi-bin/wiki/RememberMode' for more
information.  The notes produced by _Remember_ can be stored in
different ways, and Org-mode files are a good target.  Org-mode allows
you to file away notes either to a default file, or directly to the
correct location in your Org-mode outline tree.  The following
customization will tell _Remember_ to use org files as target, and to
create annotations compatible with Org-mode links.

     (setq org-directory "~/path/to/my/orgfiles/")
     (setq org-default-notes-file "~/.notes")
     (setq remember-annotation-functions '(org-remember-annotation))
     (setq remember-handler-functions '(org-remember-handler))
     (add-hook 'remember-mode-hook 'org-remember-apply-template)

   In combination with Org-mode, you can use templates to generate
different types of remember notes.  For example, if you would like to
use one template to create general TODO entries, and another one for
journal entries, you could use:

     (setq org-remember-templates
           '((?t "* TODO %?\n  %i\n  %a" "~/org/TODO.org")
             (?j "* %U %?\n\n  %i\n  %a" "~/org/JOURNAL.org")))

In these entries, the character specifies how to select the template,
the first string specifies the template, and the (optional) second
string specifies a default file (overruling `org-default-notes-file')
as a target for this note.

   When you call `M-x remember' to remember something, org will prompt
for a key to select the template and then prepare the buffer like
     * TODO
       <file:link to where you called remember>

or

     * [2006-03-21 Tue 15:37]

       <file:link to where you called remember>

See the variable `org-remember-templates' for more details.

   When you are finished composing a note with remember, you have to
press `C-c C-c' to file the note away.  The handler first prompts for a
target file - if you press <RET>, the value of `org-default-notes-file'
is used.  Then the command offers the headings tree of the selected
file.  You can either immediately press <RET> to get the note appended
to the file.  Or you can use vertical cursor motion (<up> and <down>)
and visibility cycling (<TAB>) to find a better place.  Pressing <RET>
or <left> or <right> leads to the following result.

Cursor         Key     Note gets inserted
position               
buffer-start   <RET>   as level 2 heading at end of file
on headline    <RET>   as sublevel of the heading at cursor
               <left>  as same level, before current heading
               <right> as same level, after current heading
not on         <RET>   at cursor position, level taken from context.
headline                      Or use prefix arg to specify level
                       manually.

   So a fast way to store the note is to press `C-c C-c <RET> <RET>' to
append it to the default file.  Even shorter would be `C-u C-c C-c',
which does the same without even showing the tree.  But with little
extra effort, you can push it directly to the correct location.

   Before inserting the text into a tree, the function ensures that the
text has a headline, i.e. a first line that starts with a `*'.  If not,
a headline is constructed from the current date and some additional
data.  If the variable `org-adapt-indentation' is non-nil, the entire
text is also indented so that it starts in the same column as the
headline (after the asterisks).

5 TODO items
************

Org-mode does not maintain TODO lists as a separate document.  TODO
items are an integral part of the notes file, because TODO items
usually come up while taking notes!  With Org-mode, you simply mark any
entry in a tree as being a TODO item.  In this way, the information is
not duplicated, and the entire context from which the item emerged is
always present when you check.

   Of course, this technique causes TODO items to be scattered
throughout your file.  Org-mode provides methods to give you an
overview over all things you have to do.

* Menu:

* TODO basics::                 Marking and displaying TODO entries
* TODO extensions::             Workflow and assignments
* Priorities::                  Some things are more important than others

\x1f
File: org,  Node: TODO basics,  Next: TODO extensions,  Prev: TODO items,  Up: TODO items

5.1 Basic TODO functionality
============================

Any headline can become a TODO item by starting it with the word TODO,
for example:

     *** TODO Write letter to Sam Fortune

The most important commands to work with TODO entries are:

`C-c C-t'
     Rotate the TODO state of the current item between

          ,-> (unmarked) -> TODO -> DONE --.
          '--------------------------------'

     The same rotation can also be done "remotely" from the timeline and
     agenda buffers with the `t' command key (*note Agenda commands::).  

`S-<right>'
`S-<left>'
     Select the following/preceding TODO state, similar to cycling.
     Mostly useful if more than two TODO states are possible (*note
     TODO extensions::).  

`C-c C-v'
     View TODO items in a _sparse tree_ (*note Sparse trees::).  Folds
     the entire buffer, but shows all TODO items and the headings
     hierarchy above them.  With prefix arg, show also the DONE
     entries.  With numerical prefix N, show the tree for the Nth
     keyword in the variable `org-todo-keywords'.  

`C-c a t'
     Show the global TODO list.  This collects the TODO items from all
     agenda files (*note Agenda views::) into a single buffer.  The
     buffer is in `agenda-mode', so there are commands to examine and
     manipulate the TODO entries directly from that buffer (*note
     Agenda commands::).  *Note Global TODO list::, for more
     information.

5.2 Extended use of TODO keywords
=================================

The default implementation of TODO entries is just two states: TODO and
DONE.  You can, however, use the TODO feature for more complicated
things by configuring the variables `org-todo-keywords' and
`org-todo-interpretation'.  Using special setup, you can even use TODO
keywords in different ways in different org files.

   Note that tags are another way to classify headlines in general and
TODO items in particular (*note Tags::).

* Menu:

* Workflow states::             From TODO to DONE in steps
* TODO types::                  I do this, Fred the rest
* Per file keywords::           Different files, different requirements

\x1f
File: org,  Node: Workflow states,  Next: TODO types,  Prev: TODO extensions,  Up: TODO extensions

5.2.1 TODO keywords as workflow states
--------------------------------------

You can use TODO keywords to indicate different states in the process
of working on an item, for example:

     (setq org-todo-keywords '("TODO" "FEEDBACK" "VERIFY" "DONE")
           org-todo-interpretation 'sequence)

   Changing these variables only becomes effective in a new Emacs
session.  With this setup, the command `C-c C-t' will cycle an entry
from TODO to FEEDBACK, then to VERIFY, and finally to DONE.  You may
also use a prefix argument to quickly select a specific state.  For
example `C-3 C-c C-t' will change the state immediately to VERIFY.  If
you define many keywords, you can use in-buffer completion (see *Note
Completion::) to insert these words into the buffer.

\x1f
File: org,  Node: TODO types,  Next: Per file keywords,  Prev: Workflow states,  Up: TODO extensions

5.2.2 TODO keywords as types
----------------------------

The second possibility is to use TODO keywords to indicate different
types of action items.  For example, you might want to indicate that
items are for "work" or "home".  If you are into David Allen's _Getting
Things DONE_, you might want to use todo types `NEXTACTION', `WAITING',
`MAYBE'.  Or, when you work with several people on a single project,
you might want to assign action items directly to persons, by using
their names as TODO keywords.  This would be set up like this:

     (setq org-todo-keywords '("Fred" "Sara" "Lucy" "Mike" "DONE")
           org-todo-interpretation 'type)

   In this case, different keywords do not indicate a sequence, but
rather different types.  So it is normally not useful to change from
one type to another.  Therefore, in this case the behavior of the
command `C-c C-t' is changed slightly(1).  When used several times in
succession, it will still cycle through all names.  But when you return
to the item after some time and execute `C-c C-t' again, it will switch
from each name directly to DONE.  Use prefix arguments or completion to
quickly select a specific name.  You can also review the items of a
specific TODO type in a sparse tree by using a numeric prefix to `C-c
C-v'.  For example, to see all things Lucy has to do, you would use
`C-3 C-c C-v'.  To collect Lucy's items from all agenda files into a
single buffer, you would use the prefix arg as well when creating the
global todo list: `C-3 C-c t'.

   (1) This is also true for the `t' command in the timeline and agenda
buffers.

File: org,  Node: Per file keywords,  Prev: TODO types,  Up: TODO extensions

5.2.3 Setting up TODO keywords for individual files
---------------------------------------------------

It can be very useful to use different aspects of the TODO mechanism in
different files, which is not possible with the global settings
described above.  For file-local settings, you need to add special
lines to the file which set the keywords and interpretation for that
file only.  For example, to set one of the two examples discussed
above, you need one of the following lines, starting in column zero
anywhere in the file:

     #+SEQ_TODO: TODO FEEDBACK VERIFY DONE
     #+TYP_TODO: Fred Sara Lucy Mike DONE

To make sure you are using the correct keyword, type `#+' into the
buffer and then use `M-<TAB>' completion.

   Remember that the last keyword must always mean that the item is DONE
(although you may use a different word).  Also note that in each file,
only one of the two aspects of TODO keywords can be used.  After
changing one of these lines, use `C-c C-c' with the cursor still in the
line to make the changes known to Org-mode(1).

   If you want to use very many keywords, for example when working with
a large group of people, you may split the names over several lines:

     #+TYP_TODO: Fred Sara Lucy Mike
     #+TYP_TODO: Luis George Jules Jessica
     #+TYP_TODO: Kim Arnold Peter
     #+TYP_TODO: DONE

   ---------- Footnotes ----------

   (1) Org-mode parses these lines only when Org-mode is activated
after visiting a file.  `C-c C-c' with the cursor in a line starting
with `#+' is simply restarting Org-mode, making sure that these changes
will be respected.

\x1f
File: org,  Node: Priorities,  Prev: TODO extensions,  Up: TODO items

5.3 Priorities
==============

If you use Org-mode extensively to organize your work, you may end up
with a number of TODO entries so large that you'd like to prioritize
them.  This can be done by placing a _priority cookie_ into the
headline, like this

     *** TODO [#A] Write letter to Sam Fortune

With its standard setup, Org-mode supports priorities `A', `B', and
`C'.  `A' is the highest priority.  An entry without a cookie is
treated as priority `B'.  Priorities make a difference only in the
agenda (*note Weekly/Daily agenda::).

`C-c ,'
     Set the priority of the current headline.  The command prompts for
     a priority character `A', `B' or `C'.  When you press <SPC>
     instead, the priority cookie is removed from the headline.  The
     priorities can also be changed "remotely" from the timeline and
     agenda buffer with the `,' command (*note Agenda commands::).

`S-<up>'
`S-<down>'
     Increase/decrease priority of current headline.  Note that these
     keys are also used to modify time stamps (*note Creating
     timestamps::).  Furthermore, these keys are also used by CUA-mode
     (*note Conflicts::).

File: org,  Node: Time stamps,  Next: Creating timestamps,  Prev: Timestamps,  Up: Timestamps

6.1 Time stamps, deadlines and scheduling
=========================================

A time stamp is a specification of a date (possibly with time) in a
special format, either `<2003-09-16 Tue>' or `<2003-09-16 Tue 09:39>'.
A time stamp can appear anywhere in the headline or body of an org-tree
entry.  Its presence allows entries to be shown on specific dates in
the agenda (*note Weekly/Daily agenda::).  We distinguish:

PLAIN TIME STAMP
     A simple time stamp just assigns a date/time to an item.  This is
     just like writing down an appointment in a paper agenda, or like
     writing down an event in a diary, when you want to take note of
     when something happened.  In the timeline and agenda displays, the
     headline of an entry associated with a plain time stamp will be
     shown exactly on that date.

TIME STAMP RANGE
     Two time stamps connected by `--' denote a time range.  The
     headline will be shown on the first and last day of the range, and
     on any dates that are displayed and fall in the range.  Here is an
     example:

          ** Meeting in Amsterdam
             <2004-08-23 Mon>--<2004-08-26 Thu>

TIME STAMP WITH SCHEDULED KEYWORD
     If a time stamp is preceded by the word `SCHEDULED:', it means you
     are planning to start working on that task on the given date. So
     this is not about recording an event, but about planning your
     work.  The headline will be listed under the given date.  In
     addition, a reminder that the scheduled date has passed will be
     present in the compilation for _today_, until the entry is marked
     DONE.  I.e., the task will automatically be forwarded until
     completed.

          *** TODO Call Trillian for a date on New Years Eve.
              SCHEDULED: <2004-12-25 Sat>

TIME STAMP WITH DEADLINE KEYWORD
     If a time stamp is preceded by the word `DEADLINE:', the task
     (most likely a TODO item) is supposed to be finished on that date,
     and it will be listed then.  In addition, the compilation for
     _today_ will carry a warning about the approaching or missed
     deadline, starting `org-deadline-warning-days' before the due
     date, and continuing until the entry is marked DONE.  An example:

          *** TODO write article about the Earth for the Guide
              The editor in charge is <bbdb:Ford Prefect>
              DEADLINE: <2004-02-29 Sun>

TIME STAMP WITH CLOSED KEYWORD
     When `org-log-done' is non-nil, Org-mode will automatically insert
     a special time stamp each time a TODO entry is marked done (*note
     Progress logging::).  This time stamp is enclosed in square
     brackets instead of angular brackets.

TIME RANGE WITH CLOCK KEYWORD
     When using the clock to time the work that is being done on
     specific items, time ranges preceded by the CLOCK keyword are
     inserted automatically into the file.  The time stamps are
     enclosed in square brackets instead of angular brackets.  *Note
     Clocking work time::.

\x1f
File: org,  Node: Creating timestamps,  Next: Progress logging,  Prev: Time stamps,  Up: Timestamps

6.2 Creating timestamps
=======================

For Org-mode to recognize time stamps, they need to be in the specific
format.  All commands listed below produce time stamps in the correct
format.

`C-c .'
     Prompt for a date and insert a corresponding time stamp.  When the
     cursor is at a previously used time stamp, it is updated to NOW.
     When this command is used twice in succession, a time range is
     inserted.

`C-u C-c .'
     Like `C-c .', but use the alternative format which contains date
     and time.  The default time can be rounded to multiples of 5
     minutes, see the option `org-time-stamp-rounding-minutes'.

`C-c !'
     Like `C-c .', but insert an inactive time stamp not triggering the
     agenda.

`C-c <'
     Insert a time stamp corresponding to the cursor date in the
     Calendar.

`C-c >'
     Access the Emacs calendar for the current date.  If there is a
     timestamp in the current line, goto the corresponding date instead.

`C-c C-o'
     Access the agenda for the date given by the time stamp at point
     (*note Weekly/Daily agenda::).

`C-c C-d'
     Insert `DEADLINE' keyword along with a stamp.  The insertion will
     happen in the line directly following the headline.

`C-c C-w'
     Create a sparse tree with all deadlines that are either past-due,
     or which will become due within `org-deadline-warning-days'.  With
     `C-u' prefix, show all deadlines in the file.  With a numeric
     prefix, check that many days.  For example, `C-1 C-c C-w' shows
     all deadlines due tomorrow.

`C-c C-s'
     Insert `SCHEDULED' keyword along with a stamp.  The insertion will
     happen in the line directly following the headline.  Any CLOSED
     timestamp will be removed.

`S-<left>'
`S-<right>'
     Change date at cursor by one day.  These key bindings conflict with
     CUA-mode (*note Conflicts::).

`S-<up>'
`S-<down>'
     Change the item under the cursor in a timestamp.  The cursor can
     be on a year, month, day, hour or minute.  Note that if the cursor
     is not at a time stamp, these same keys modify the priority of an
     item.  (*note Priorities::). The key bindings also conflict with
     CUA-mode (*note Conflicts::).

`C-c C-y'
     Evaluate a time range by computing the difference between start and
     end.  With prefix arg, insert result after the time range (in a
     table: into the following column).

   When Org-mode prompts for a date/time, the function reading your
input will replace anything you choose not to specify with the current
date and time.  For details, see the documentation string of
`org-read-date'.  Also, a calender will pop up to allow selecting a
date.  The calendar can be fully controlled from the minibuffer, and a
date can be selected with the following commands:

`<'
     Scroll calendar backwards by one month.  

`>'
     Scroll calendar forwards by one month.  

`mouse-1'
     Select date by clicking on it.  

`S-<right>'
     One day forward.  

`S-<left>'
     One day back.  

`S-<down>'
     One week forward.  

`S-<up>'
     One week back.  

`M-S-<right>'
     One month forward.  

`M-S-<left>'
     One month back.  

`<RET>'
     Choose date in calendar (only if nothing typed into minibuffer).

6.3 Progress Logging
====================

Org-mode can automatically record a time stamp when you mark a TODO item
as DONE.  You can also measure precisely the time you spent on specific
items in a project by starting and stopping a clock when you start and
stop working on an aspect of a project.

* Menu:

* Closing items::               When was this entry marked DONE?
* Clocking work time::          When exactly did you work on this item?

\x1f
File: org,  Node: Closing items,  Next: Clocking work time,  Prev: Progress logging,  Up: Progress logging

6.3.1 Closing items
-------------------

If you want to keep track of _when_ a certain TODO item was finished,
turn on logging with

     (setq org-log-done t)

Then each time you turn a TODO entry into DONE using either `C-c C-t'
in the Org-mode buffer or `t' in the agenda buffer, a line `CLOSED:
[timestamp]' will be inserted just after the headline.  If you turn the
entry back into a TODO item again through further state cycling, that
line will be removed again.  In the timeline (*note Timeline::) and in
the agenda (*note Weekly/Daily agenda::), you can then use the `l' key
to display the TODO items closed on each day, giving you an overview of
what has been done on a day.

\x1f
File: org,  Node: Clocking work time,  Prev: Closing items,  Up: Progress logging

6.3.2 Clocking work time
------------------------

Org-mode allows you to clock the time you spent on specific tasks in a
project.  When you start working on an item, you can start the clock.
When you stop working on that task, or when you mark the task done, the
clock is stopped and the corresponding time interval is recorded.  It
also computes the total time spent on each subtree of a project.

`C-c C-x C-i'
     Start the clock on the current item (clock-in).  This inserts the
     CLOCK keyword together with a timestamp.  

`C-c C-x C-o'
     Stop the clock (clock-out).  The inserts another timestamp at the
     same location where the clock was last started.  It also directly
     computes the resulting time in inserts it after the time range as
     `=> HH:MM'.  

`C-c C-t'
     Changing the TODO state of an item to DONE automatically stops the
     clock if it is running in this same item.  

`C-c C-x C-x'
     Cancel the current clock.  This is useful if a clock was started by
     mistake, or if you ended up working on something else.  

`C-c C-x C-d'
     Display time summaries for each subtree in the current buffer.
     This puts overlays at the end of each headline, showing the total
     time recorded under that heading, including the time of any
     subheadings. You can use visibility cycling to study the tree, but
     the overlays disappear automatically when the buffer is changed.  

`C-c C-x C-r'
     Insert a dynamic block containing a clock report as an org-mode
     table into the current file.
          #+BEGIN: clocktable :maxlevel 2 :emphasize nil

          #+END: clocktable
     If such a block already exists, its content is replaced by the new
     table.  The `BEGIN' line can specify options:
          :maxlevels   Maximum level depth to which times are listed in the table.
          :emphasize   When `t', emphasize level one and level two items

   The `l' key may be used in the timeline (*note Timeline::) and in
the agenda (*note Weekly/Daily agenda::) to show which tasks have been
worked on or closed during a day.

7 Tags
******

If you wish to implement a system of labels and contexts for
cross-correlating information, an excellent way is to assign tags to
headlines.  Org-mode has extensive support for using tags.

   Every headline can contain a list of tags, at the end of the
headline.  Tags are normal words containing letters, numbers, `_', and
`@'.  Tags must be preceded and followed by a single colon; like
`:WORK:'.  Several tags can be specified like `:WORK:URGENT:'.

* Menu:

* Tag inheritance::             Tags use the tree structure of the outline
* Setting tags::                How to assign tags to a headline
* Tag searches::                Searching for combinations of tags

\x1f
File: org,  Node: Tag inheritance,  Next: Setting tags,  Prev: Tags,  Up: Tags

7.1 Tag inheritance
===================

Tags make use of the hierarchical structure of outline trees.  If a
heading has a certain tag, all subheadings will inherit the tag as
well.  For example, in the list

     * Meeting with the French group      :WORK:
     ** Summary by Frank                  :BOSS:NOTES:
     *** TODO Prepare slides for him      :ACTION:

the final heading will have the tags `:WORK:', `:BOSS:', `:NOTES:', and
`:ACTION:'.  When executing tag searches and Org-mode finds that a
certain headline matches the search criterion, it will not check any
sublevel headline, assuming that these likely also match, and that the
list of matches can become very long.  This may not be what you want,
however, and you can influence inheritance and searching using the
variables `org-use-tag-inheritance' and `org-tags-match-list-sublevels'.

\x1f
File: org,  Node: Setting tags,  Next: Tag searches,  Prev: Tag inheritance,  Up: Tags

7.2 Setting tags
================

Tags can simply be typed into the buffer at the end of a headline.
After a colon, `M-<TAB>' offers completion on tags.  There is also a
special command for inserting tags:

`C-c C-c'
     Enter new tags for the current headline.  Org-mode will either
     offer completion or a special single-key interface for setting
     tags, see below.  After pressing <RET>, the tags will be inserted
     and aligned to `org-tags-column'.  When called with a `C-u'
     prefix, all tags in the current buffer will be aligned to that
     column, just to make things look nice.  TAGS are automatically
     realigned after promotion, demotion, and TODO state changes (*note
     TODO basics::).

   Org will support tag insertion based on a _list of tags_.  By
default this list is constructed dynamically, containing all tags
currently used in the buffer.  You may also globally specify a hard list
of tags with the variable `org-tag-alist'.  Finally you can set the
allowed tags for a given file with lines like

     #+TAGS: @WORK @HOME @TENNISCLUB
     #+TAGS: Laptop Car PC Sailboat

   The default support method is minibuffer completion.  However,
Org-mode also implements a much better method: _fast tag selection_.
This method allows to select and deselect tags with a single key per
tag.  To function efficiently, you should assign unique keys to all
tags.  This can be done globally with

     (setq org-tag-alist '(("@WORK" . ?w) ("@HOME" . ?h) ("Laptop" . ?l)))

or on a per-file basis with

     #+TAGS: @WORK(w)  @HOME(h)  @TENNISCLUB(t)  Laptop(l)  PC(p)

You can also group together tags that are mutually exclusive.  With
curly braces(1)

     #+TAGS: { @WORK(w)  @HOME(h)  @TENNISCLUB(t) }  Laptop(l)  PC(p)

you indicate that at most one of `@WORK', `@HOME', and `@SAILBOAT'
should be selected.

Don't forget to press `C-c C-c' with the cursor in one of these lines
to activate any changes.

   If at least one tag has a selection key, pressing `C-c C-c' will
automatically present you with a special interface, listing inherited
tags, the tags of the current headline, and a list of all legal tags
with corresponding keys(2).  Pressing keys for the tags will add or
remove them from the list of tags in the current line.  Selecting a tag
in a group of mutually exclusive tags will turn off any other tags from
that group.  <SPC> clears all tags for this line, `RET' accepts the
modified set, and `C-g' aborts without installing changes.  This method
lets you assign tags to a headline with very few keys.  With the above
setup, you could clear the current tags and set `@HOME', `Laptop' and
`PC' tags with just the following keys: `C-c C-c <SPC> h l p <RET>'.
Switching from `@HOME' to `@WORK' would be done with `C-c C-c w <RET>'.

   What if you have globally defined your preferred set of tags using
the variable `org-tag-alist', but would like to use a dynamic tag list
in a specific file?  Just add an empty TAGS option line to that file:

     #+TAGS:

   ---------- Footnotes ----------

   (1) In `org-mode-alist' use `'(:startgroup)' and `'(:endgroup)',
respectively.  Several groups are allowed.

   (2) Keys will automatically assigned to tags which have no
configured keys.

7.3 Tag searches
================

Once a tags system has been set up, it can be used to collect related
information into special lists.

`C-c \'
     Create a sparse tree with all headlines matching a tags search.  

`C-c a m'
     Create a global list of tag matches from all agenda files.  *Note
     Matching headline tags::.  

`C-c a M'
     Create a global list of tag matches from all agenda files, but
     check only TODO items and force checking subitems (see variable
     `org-tags-match-list-sublevels').

   A tags search string can use Boolean operators `&' for AND and `|'
for OR.  `&' binds more strongly than `|'.  Parenthesis are currently
not implemented.  A tag may also be preceded by `-', to select against
it, and `+' is syntactic sugar for positive selection.  The AND
operator `&' is optional when `+' or `-' is present.  For example,
`+WORK-BOSS' would select all headlines that are tagged `:WORK:', but
discard those also tagged `:BOSS:'.  The search string `WORK|LAPTOP'
selects all lines tagged `:WORK:' or `:LAPTOP:'.  The string
`WORK|LAPTOP&NIGHT' requires that the `:LAPTOP:' lines are also tagged
`NIGHT'.

File: org,  Node: Agenda views,  Next: Embedded LaTeX,  Prev: Tags,  Up: Top

8 Agenda Views
**************

Due to the way Org-mode works, TODO items, time-stamped items, and
tagged headlines can be scattered throughout a file or even a number of
files.  To get an overview over open action items, or over events that
are important for a particular date, this information must be collected,
sorted and displayed in an organized way.

   Org-mode can select items based on various criteria, and display them
in a separate buffer.  Three different views are provided:

   * an _agenda_ that is like a calendar and shows information for
     specific dates

   * a _TODO list_ that covers all unfinished action items, and

   * a _tags view_ that shows information based on the tags associated
     with headlines in the outline tree.

The extracted information is displayed in a special _agenda buffer_.
This buffer is read-only, but provides commands to visit the
corresponding locations in the original Org-mode files, and even to
edit these files remotely.

* Menu:

* Agenda files::                Files being searched for agenda information
* Agenda dispatcher::           Keyboard access to agenda views
* Weekly/Daily agenda::         The calendar page with current tasks
* Global TODO list::            All unfinished action items
* Matching headline tags::      Structured information with fine-tuned search
* Timeline::                    Time-sorted view for single file
* Agenda commands::             Remote editing of org trees

\x1f
File: org,  Node: Agenda files,  Next: Agenda dispatcher,  Prev: Agenda views,  Up: Agenda views

8.1 Agenda files
================

The information to be shown is collected from all _agenda files_, the
files listed in the variable `org-agenda-files'(1).  Thus even if you
only work with a single Org-mode file, this file should be put into
that list(2).  You can customize `org-agenda-files', but the easiest
way to maintain it is through the following commands

`C-c ['
     Add current file to the list of agenda files.  The file is added to
     the front of the list.  If it was already in the list, it is moved
     to the front.  With prefix arg, file is added/moved to the end.  

`C-c ]'
     Remove current file from the list of agenda files.  

`C-,'
     Cycle through agenda file list, visiting one file after the other.

The Org menu contains the current list of files and can be used to
visit any of them.

   ---------- Footnotes ----------

   (1) If the value of that variable is not a list, but a single file
name, then the list of agenda files will be maintained in that external
file.

   (2) When using the dispatcher pressing `1' before selecting a
command will actually limit the command to the current file, and ignore
`org-agenda-files' until the next dispatcher command.

\x1f
File: org,  Node: Agenda dispatcher,  Next: Weekly/Daily agenda,  Prev: Agenda files,  Up: Agenda views

8.2 The agenda dispatcher
=========================

The views are created through a dispatcher that should be bound to a
global key, for example `C-c a' (*note Installation::).  In the
following we will assume that `C-c a' is indeed how the dispatcher is
accessed and list keyboard access to commands accordingly.  After
pressing `C-c a', an additional letter is required to execute a
command.  The dispatcher offers the following default commands:
`a'
     Create the calendar-like agenda (*note Weekly/Daily agenda::).

`t / T'
     Create a list of all TODO items (*note Global TODO list::).

`m / M'
     Create a list of headlines matching a TAGS expression (*note
     Matching headline tags::).

   You can also define custom commands that will be accessible through
the dispatcher, just like the default commands.  Custom commands are
global searches for tags and specific TODO keywords, or a variety of
sparse tree creating commands (*note Sparse trees::).  As sparse trees
are only defined for a single org-mode file, these latter commands act
on the current buffer instead of the list of agenda files.

   Custom commands are configured in the variable
`org-agenda-custom-commands'.  You can customize this variable, for
example by pressing `C-c a C'.  You can also directly set it with Emacs
Lisp in `.emacs'.  For example:

     (setq org-agenda-custom-commands
           '(("w" todo "WAITING")
             ("u" tags "+BOSS-URGENT")
             ("U" tags-tree "+BOSS-URGENT")
             ("f" occur-tree "\\<FIXME\\>")))

will define `C-c a w' as a global search for TODO entries with
`WAITING' as the TODO keyword, `C-c a u' as a global tags search for
headlines marked `:BOSS:' but not `:URGENT:', `C-c a U' to do the same
search but only in the current buffer and display the result as a
sparse tree, and `C-c a f' to create a sparse tree with all entries
containing the word `FIXME'.  For more information, look at the
documentation string of the variable `org-agenda-custom-commands'.

\x1f
File: org,  Node: Weekly/Daily agenda,  Next: Global TODO list,  Prev: Agenda dispatcher,  Up: Agenda views

8.3 The weekly/daily agenda
===========================

The purpose of the weekly/daily _agenda_ is to act like a page of a
paper agenda, showing all the tasks for the current week or day.

`C-c a a'
     Compile an agenda for the current week from a list of org files.
     The agenda shows the entries for each day.  With a `C-u' prefix (or
     when the variable `org-agenda-include-all-todo' is `t'), all
     unfinished TODO items (including those without a date) are also
     listed at the beginning of the buffer, before the first date.

   Remote editing from the agenda buffer means, for example, that you
can change the dates of deadlines and appointments from the agenda
buffer.  The commands available in the Agenda buffer are listed in
*Note Agenda commands::.

* Menu:

* Categories::                  Not all tasks are equal
* Time-of-day specifications::  How the agenda knows the time
* Calendar/Diary integration::  Integrating Anniversaries and more
* Sorting of agenda items::     The order of things

\x1f
File: org,  Node: Categories,  Next: Time-of-day specifications,  Prev: Weekly/Daily agenda,  Up: Weekly/Daily agenda

8.3.1 Categories
----------------

In the agenda buffer, each entry is preceded by a _category_, which is
derived from the file name.  The category can also be set with a
special line anywhere in the buffer, looking like this:

     #+CATEGORY: Thesis

   If there are several such lines in a file, each specifies the
category for the text below it (but the first category also applies to
any text before the first CATEGORY line).  The display in the agenda
buffer looks best if the category is not longer than 10 characters.

\x1f
File: org,  Node: Time-of-day specifications,  Next: Calendar/Diary integration,  Prev: Categories,  Up: Weekly/Daily agenda

8.3.2 Time-of-Day Specifications
--------------------------------

Org-mode checks each agenda item for a time-of-day specification.  The
time can be part of the time stamp that triggered inclusion into the
agenda, for example as in `<2005-05-10 Tue 19:00>'.  Time ranges can be
specified with two time stamps, like
`<2005-05-10 Tue 20:30>--<2005-05-10 Tue 22:15>'.

   In the headline of the entry itself, a time(range) may also appear as
plain text (like `12:45' or a `8:30-1pm'.  If the agenda integrates the
Emacs diary (*note Calendar/Diary integration::), time specifications
in diary entries are recognized as well.

   For agenda display, Org-mode extracts the time and displays it in a
standard 24 hour format as part of the prefix.  The example times in
the previous paragraphs would end up in the agenda like this:

         8:30-13:00 Arthur Dent lies in front of the bulldozer
        12:45...... Ford Prefect arrives and takes Arthur to the pub
        19:00...... The Vogon reads his poem
        20:30-22:15 Marwin escorts the Hitchhikers to the bridge

   If the agenda is in single-day mode, or for the display of today, the
timed entries are embedded in a time grid, like

         8:00...... ------------------
         8:30-13:00 Arthur Dent lies in front of the bulldozer
        10:00...... ------------------
        12:00...... ------------------
        12:45...... Ford Prefect arrives and takes Arthur to the pub
        14:00...... ------------------
        16:00...... ------------------
        18:00...... ------------------
        19:00...... The Vogon reads his poem
        20:00...... ------------------
        20:30-22:15 Marwin escorts the Hitchhikers to the bridge

   The time grid can be turned on and off with the variable
`org-agenda-use-time-grid', and can be configured with
`org-agenda-time-grid'.

\x1f
File: org,  Node: Calendar/Diary integration,  Next: Sorting of agenda items,  Prev: Time-of-day specifications,  Up: Weekly/Daily agenda

8.3.3 Calendar/Diary integration
--------------------------------

Emacs contains the calendar and diary by Edward M. Reingold.  The
calendar displays a three-month calendar with holidays from different
countries and cultures.  The diary allows you to keep track of
anniversaries, lunar phases, sunrise/set, recurrent appointments
(weekly, monthly) and more.  In this way, it is quite complementary to
Org-mode.  It can be very useful to combine output from Org-mode with
the diary.

   In order to include entries from the Emacs diary into Org-mode's
agenda, you only need to customize the variable

     (setq org-agenda-include-diary t)

After that, everything will happen automatically.  All diary entries
including holidays, anniversaries etc will be included in the agenda
buffer created by Org-mode.  <SPC>, <TAB>, and <RET> can be used from
the agenda buffer to jump to the diary file in order to edit existing
diary entries.  The `i' command to insert new entries for the current
date works in the agenda buffer, as well as the commands `S', `M', and
`C' to display Sunrise/Sunset times, show lunar phases and to convert
to other calendars, respectively.  `c' can be used to switch back and
forth between calendar and agenda.

\x1f
File: org,  Node: Sorting of agenda items,  Prev: Calendar/Diary integration,  Up: Weekly/Daily agenda

8.3.4 Sorting of agenda items
-----------------------------

The entries for each day are sorted.  The default order is to first
collect all items containing an explicit time-of-day specification.
These entries will be shown at the beginning of the list, as a
_schedule_ for the day.  After that, items remain grouped in
categories, in the sequence given by `org-agenda-files'.  Within each
category, items are sorted by priority (*note Priorities::).

   The priority is a numerical quantity composed of the base priority
(2000 for priority `A', 1000 for `B', and 0 for `C'), plus additional
increments for overdue scheduled or deadline items.

   Sorting can be customized using the variable
`org-agenda-sorting-strategy'.

\x1f
File: org,  Node: Global TODO list,  Next: Matching headline tags,  Prev: Weekly/Daily agenda,  Up: Agenda views

8.4 The global TODO list
========================

The global TODO list contains all unfinished TODO items, formatted and
collected into a single place.

`C-c a t'
     Show the global TODO list.  This collects the TODO items from all
     agenda files (*note Agenda views::) into a single buffer.  The
     buffer is in `agenda-mode', so there are commands to examine and
     manipulate the TODO entries directly from that buffer (*note
     Agenda commands::).  

`C-c a T'
     Like the above, but allows selection of a specific TODO keyword.
     You can also do this by specifying a prefix argument to `C-c a t'.
     With a `C-u' prefix you are prompted for a keyword.  With a
     numeric prefix, the Nth keyword in `org-todo-keywords' is selected.  The
     `r' key in the agenda buffer regenerates it, and you can give a
     prefix argument to this command to change the selected TODO
     keyword, for example `3 r'.  If you often need a search for a
     specific keyword, define a custom command for it (*note Agenda
     dispatcher::).

   Remote editing of TODO items means that you can change the state of a
TODO entry with a single key press.  The commands available in the TODO
list are described in *Note Agenda commands::.

\x1f
File: org,  Node: Matching headline tags,  Next: Timeline,  Prev: Global TODO list,  Up: Agenda views

8.5 Matching headline tags
==========================

If headlines in the agenda files are marked with _tags_ (*note Tags::),
you can select headlines based on the tags that apply to them and
collect them into an agenda buffer.

`C-c a m'
     Produce a list of all headlines that match a given set of tags.
     The command prompts for a selection criterion, which is a boolean
     logic expression with tags, like `+WORK+URGENT-WITHBOSS' or
     `WORK|HOME' (*note Tags::).  If you often need a specific search,
     define a custom command for it (*note Agenda dispatcher::).  

`C-c a M'
     Like `C-c a m', but only select headlines that are also TODO items
     and force checking subitems (see variable
     `org-tags-match-list-sublevels'.

   The commands available in the tags list are described in *Note
Agenda commands::.

\x1f
File: org,  Node: Timeline,  Next: Agenda commands,  Prev: Matching headline tags,  Up: Agenda views

8.6 Timeline for a single file
==============================

The timeline is not really an agenda view, because it only summarizes
items from a single Org-mode file.  But it also uses the agenda buffer
and provides similar commands, so we discuss it here.  The timeline
shows all time-stamped items in a single Org-mode file (or the selected
part of it), in a _time-sorted view_.  The main purpose of this command
is to give an overview over events in a project.

`C-c C-r'
     Show a time-sorted view of the org file, with all time-stamped
     items.  When called with a `C-u' prefix, all unfinished TODO
     entries (scheduled or not) are also listed under the current date.

The commands available in the timeline buffer are listed in *Note
Agenda commands::.

\x1f
File: org,  Node: Agenda commands,  Prev: Timeline,  Up: Agenda views

8.7 Commands in the agenda buffer
=================================

Entries in the agenda buffer are linked back to the org file or diary
file where they originate.  You are not allowed to edit the agenda
buffer itself, but commands are provided to show and jump to the
original entry location, and to edit the org-files "remotely" from the
agenda buffer.  In this way, all information is stored only once,
removing the risk that your agenda and note files may diverge.

   Some commands can be executed with mouse clicks on agenda lines.  For
the other commands, the cursor needs to be in the desired line.

Motion
......

`n'
     Next line (same as <up>).  

`p'
     Previous line (same as <down>).

View/GoTo org file
..................

`mouse-3'
`<SPC>'
     Display the original location of the item in another window.

`L'
     Display original location and recenter that window.

`mouse-2'
`mouse-1'
`<TAB>'
     Go to the original location of the item in another window.  Under
     Emacs 22, `mouse-1' will also works for this.

`<RET>'
     Go to the original location of the item and delete other windows.

`f'
     Toggle Follow mode.  In Follow mode, as you move the cursor through
     the agenda buffer, the other window always shows the corresponding
     location in the org file.  The initial setting for this mode in new
     agenda buffers can be set with the variable
     `org-agenda-start-with-follow-mode'.

`l'
     Toggle Logbook mode.  In Logbook mode, entries that where marked
     DONE while logging was on (variable `org-log-done') are shown in
     the agenda, as are entries that have been clocked on that day.

Change display
..............

`o'
     Delete other windows.

`w'
     Switch to weekly view (7 days displayed together).

`d'
     Switch to daily view (just one day displayed).

`D'
     Toggle the inclusion of diary entries.  See *Note Calendar/Diary
     integration::.

`g'
     Toggle the time grid on and off.  See also the variables
     `org-agenda-use-time-grid' and `org-agenda-time-grid'.

`r'
     Recreate the agenda buffer, for example to reflect the changes
     after modification of the time stamps of items with S-<left> and
     S-<right>.  When the buffer is the global todo list, a prefix
     argument is interpreted to create a selective list for a specific
     TODO keyword.

`s'
     Save all Org-mode buffers in the current Emacs session.

`<right>'
     Display the following `org-agenda-ndays' days.  For example, if
     the display covers a week, switch to the following week.  With
     prefix arg, go forward that many times `org-agenda-ndays' days.

`<left>'
     Display the previous dates.

`.'
     Goto today.

Remote editing
..............

`0-9'
     Digit argument.

`t'
     Change the TODO state of the item, both in the agenda and in the
     original org file.

`T'
     Show all tags associated with the current item.  Because of
     inheritance, this may be more than the tags listed in the line
     itself.

`:'
     Set tags for the current headline.

`a'
     Toggle the ARCHIVE tag for the current headline.

`,'
     Set the priority for the current item.  Org-mode prompts for the
     priority character. If you reply with <SPC>, the priority cookie
     is removed from the entry.

`p'
     Display weighted priority of current item.

`+'
`S-<up>'
     Increase the priority of the current item.  The priority is
     changed in the original buffer, but the agenda is not resorted.
     Use the `r' key for this.

`-'
`S-<down>'
     Decrease the priority of the current item.

`C-c C-s'
     Schedule this item

`C-c C-d'
     Set a deadline for this item.

`S-<right>'
     Change the time stamp associated with the current line by one day
     into the future.  With prefix argument, change it by that many
     days.  For example, `3 6 5 S-<right>' will change it by a year.
     The stamp is changed in the original org file, but the change is
     not directly reflected in the agenda buffer.  Use the `r' key to
     update the buffer.

`S-<left>'
     Change the time stamp associated with the current line by one day
     into the past.

`>'
     Change the time stamp associated with the current line to today.
     The key `>' has been chosen, because it is the same as `S-.' on my
     keyboard.

`I'
     Start the clock on the current item.  If a clock is running
     already, it is stopped first.  

`O'
     Stop the previously started clock.  

`X'
     Cancel the currently running clock.

Calendar commands
.................

`c'
     Open the Emacs calendar and move to the date at the agenda cursor.

`c'
     When in the calendar, compute and show the Org-mode agenda for the
     date at the cursor.

`i'
     Insert a new entry into the diary.  Prompts for the type of entry
     (day, weekly, monthly, yearly, anniversary, cyclic) and creates a
     new entry in the diary, just as `i d' etc. would do in the
     calendar.  The date is taken from the cursor position.

`M'
     Show the phases of the moon for the three months around current
     date.

`S'
     Show sunrise and sunset times.  The geographical location must be
     set with calendar variables, see documentation of the Emacs
     calendar.

`C'
     Convert the date at cursor into many other cultural and historic
     calendars.

`H'
     Show holidays for three month around the cursor date.

`C-c C-x C-c'
     Export a single iCalendar file containing entries from all agenda
     files.

Quit and Exit
.............

`q'
     Quit agenda, remove the agenda buffer.

`x'
     Exit agenda, remove the agenda buffer and all buffers loaded by
     Emacs for the compilation of the agenda.  Buffers created by the
     user to visit org files will not be removed.

9 Embedded LaTeX
****************

Plain ASCII is normally sufficient for almost all note taking.  One
exception, however, are scientific notes which need to be able to
contain mathematical symbols and the occasional formula.  LaTeX(1) is
widely used to typeset scientific documents. Org-mode supports
embedding LaTeX code into its files, because many academics are used to
read LaTeX source code, and because it can be readily processed into
images for HTML production.

   It is not necessary to mark LaTeX macros and code in any special way.
If you observe a few conventions, Org-mode knows how to find it and what
to do with it.

* Menu:

* Math symbols::                TeX macros for symbols and Greek letters
* Subscripts and Superscripts::  Simple syntax for raising/lowering text
* LaTeX fragments::             Complex formulas made easy
* Processing LaTeX fragments::  Previewing LaTeX processing
* CDLaTeX mode::                Speed up entering of formulas

   ---------- Footnotes ----------

   (1) LaTeX is a macro system based on Donald E. Knuth's TeX system.
Many of the features described here as "LaTeX" are really from TeX, but
for simplicity I am blurring this distinction.

\x1f
File: org,  Node: Math symbols,  Next: Subscripts and Superscripts,  Prev: Embedded LaTeX,  Up: Embedded LaTeX

9.1 Math symbols
================

You can use LaTeX macros to insert special symbols like `\alpha' to
indicate the Greek letter, or `\to' to indicate an arrow.  Completion
for these macros is available, just type `\' and maybe a few letters,
and press `M-<TAB>' to see possible completions.  Unlike LaTeX code,
Org-mode allows these macros to be present without surrounding math
delimiters, for example:

     Angles are written as Greek letters \alpha, \beta and \gamma.

   During HTML export (*note HTML export::), these symbols are
translated into the proper syntax for HTML, for the above examples this
is `&alpha;' and `&rarr;', respectively.

\x1f
File: org,  Node: Subscripts and Superscripts,  Next: LaTeX fragments,  Prev: Math symbols,  Up: Embedded LaTeX

9.2 Subscripts and Superscripts
===============================

Just like in LaTeX, `^' and `_' are used to indicate super- and
subscripts.  Again, these can be used without embedding them in
math-mode delimiters.  To increase the readability of ASCII text, it is
not necessary (but OK) to surround multi-character sub- and superscripts
with curly braces.  For example

     The mass if the sun is M_sun = 1.989 x 10^30 kg.  The radius of
     the sun is R_{sun} = 6.96 x 10^8 m.

   To avoid interpretation as raised or lowered text, you can quote `^'
and `_' with a backslash: `\_' and `\^'.

   During HTML export (*note HTML export::), subscript and superscripts
are surrounded with `<sub>' and `<sup>' tags, respectively.

\x1f
File: org,  Node: LaTeX fragments,  Next: Processing LaTeX fragments,  Prev: Subscripts and Superscripts,  Up: Embedded LaTeX

9.3 LaTeX fragments
===================

With symbols, sub- and superscripts, HTML is pretty much at its end when
it comes to representing mathematical formulas.  More complex
expressions need a dedicated formula processor.  To this end, Org-mode
can contain arbitrary LaTeX fragments.  It provides commands to preview
the typeset result of these fragments, and upon export to HTML, all
fragments will be converted to images and inlined into the HTML
document.  For this to work you need to be on a system with a working
LaTeX installation.  You also need the `dvipng' program, available at
`http://sourceforge.net/projects/dvipng/'.

   LaTeX fragments don't need any special marking at all.  The following
snippets will be identified as LaTeX source code:
   * Environments of any kind.  The only requirement is that the
     `\begin' statement appears on a new line, preceded by only
     whitespace.

   * Text within the usual LaTeX math delimiters.  To avoid conflicts
     with currency specifications, single `$' characters are only
     recognized as math delimiters if the enclosed text contains at
     most two line breaks, is directly attached to the `$' characters
     with no whitespace in between, and if the closing `$' is followed
     by whitespace or punctuation.  For the other delimiters, there is
     no such restriction, so when in doubt, use `\(...\)' as inline
     math delimiters.

For example:

     \begin{equation}                          % arbitrary environments,
     x=\sqrt{b}                                % even tables, figures
     \end{equation}                            % etc

     If $a^2=b$ and \( b=2 \), then the solution must be
     either $$ a=+\sqrt{2} $$ or \[ a=-\sqrt{2} \].

If you need any of the delimiter ASCII sequences for other purposes, you
can configure the option `org-format-latex-options' to deselect the
ones you do not wish to have interpreted by the LaTeX converter.

9.4 Processing LaTeX fragments
==============================

LaTeX fragments can be processed to produce a preview images of the
typeset expressions:

`C-c C-x C-l'
     Produce a preview image of the LaTeX fragment at point and overlay
     it over the source code.  If there is no fragment at point,
     process all fragments in the current entry (between two
     headlines).  When called with a prefix argument, process the
     entire subtree.  When called with two prefix arguments, or when
     the cursor is before the first headline, process the entire buffer.  

`C-c C-c'
     Remove the overlay preview images.

   During HTML export (*note HTML export::), all LaTeX fragments are
converted into images and inlined into the document if the following
setting is active:

     (setq org-export-with-LaTeX-fragments t)

\x1f
File: org,  Node: CDLaTeX mode,  Prev: Processing LaTeX fragments,  Up: Embedded LaTeX

9.5 Using CDLaTeX to enter math
===============================

CDLaTeX-mode is a minor mode that is normally used in combination with a
major LaTeX mode like AUCTeX in order to speed-up insertion of
environments and math templates.  Inside Org-mode, you can make use of
some of the features of cdlatex-mode.  You need to install `cdlatex.el'
and `texmathp.el' (the latter comes also with AUCTeX) from
`http://www.astro.uva.nl/~dominik/Tools/cdlatex'.  Don't turn
cdlatex-mode itself under Org-mode, but use the light version
`org-cdlatex-mode' that comes as part of Org-mode.  Turn it on for the
current buffer with `M-x org-cdlatex-mode', or for all Org-mode files
with

     (add-hook 'org-mode-hook 'turn-on-org-cdlatex)

   When this mode is enabled, the following features are present (for
more details see the documentation of cdlatex-mode):
   * Environment templates can be inserted with `C-c {'.

   * The <TAB> key will do template expansion if the cursor is inside a
     LaTeX fragment(1).  For example, <TAB> will expand `fr' to
     `\frac{}{}' and position the cursor correctly inside the first
     brace.  Another <TAB> will get you into the second brace.  Even
     outside fragments, <TAB> will expand environment abbreviations at
     the beginning of a line.  For example, if you write `equ' at the
     beginning of a line and press <TAB>, this abbreviation will be
     expanded to an `equation' environment.  To get a list of all
     abbreviations, type `M-x cdlatex-command-help'.

   * Pressing `_' and `^' inside a LaTeX fragment will insert these
     characters together with a pair of braces.  If you use <TAB> to
     move out of the braces, and if the braces surround only a single
     character or macro, they are removed again (depending on the
     variable `cdlatex-simplify-sub-super-scripts').

   * Pressing the backquote ``' followed by a character inserts math
     macros, also outside LaTeX fragments.  If you wait more than 1.5
     seconds after the backquote, a help window will pop up.

   * Pressing the normal quote `'' followed by another character
     modifies the symbol before point with an accent or a font.  If you
     wait more than 1.5 seconds after the backquote, a help window will
     pop up.  Character modification will work only inside LaTeX
     fragments, outside the quote is normal.

   ---------- Footnotes ----------

   (1) Org-mode has a method to test if the cursor is inside such a
fragment, see the documentation of the function
`org-inside-LaTeX-fragment-p'.

10 Exporting
************

Org-mode documents can be exported into a variety of other formats.  For
printing and sharing of notes, ASCII export produces a readable and
simple version of an Org-mode file.  HTML export allows you to publish a
notes file on the web, while the XOXO format provides a solid base for
exchange with a broad range of other applications.  To incorporate
entries with associated times like deadlines or appointments into a
desktop calendar program like iCal, Org-mode can also produce extracts
in the iCalendar format.  Currently Org-mode only supports export, not
import of these different formats.

   When exporting, Org-mode uses special conventions to enrich the
output produced.  *Note Text interpretation::, for more details.

* Menu:

* ASCII export::                Exporting to plain ASCII
* HTML export::                 Exporting to HTML

\x1f
File: org,  Node: ASCII export,  Next: HTML export,  Prev: Exporting,  Up: Exporting

10.1 ASCII export
=================

ASCII export produces a simple and very readable version of an Org-mode
file.

`C-c C-x a'
     Export as ASCII file.  If there is an active region, only the
     region will be exported.  For an org file `myfile.org', the ASCII
     file will be `myfile.txt'.  The file will be overwritten without
     warning.  

`C-c C-x v a'
     Export only the visible part of the document.

   In the exported version, the first 3 outline levels will become
headlines, defining a general document structure.  Additional levels
will be exported as itemized lists.  If you want that transition to
occur at a different level, specify it with a prefix argument.  For
example,

     C-1 C-c C-x a

creates only top level headlines and does the rest as items.  When
headlines are converted to items, the indentation of the text following
the headline is changed to fit nicely under the item.  This is done with
the assumption that the first bodyline indicates the base indentation of
the body text.  Any indentation larger than this is adjusted to preserve
the layout relative to the first line.  Should there be lines with less
indentation than the first, these are left alone.

\x1f
File: org,  Node: HTML export,  Next: XOXO export,  Prev: ASCII export,  Up: Exporting

10.2 HTML export
================

Org-mode contains an HTML (XHTML 1.0 strict) exporter with extensive
HTML formatting, in ways similar to John Grubers _markdown_ language,
but with additional support for tables.

`C-c C-x h'
     Export as HTML file `myfile.html'.  

`C-c C-x b'
     Export as HTML file and open it with a browser.  

`C-c C-x v h'

`C-c C-x v b'
     Export only the visible part of the document.

   In the exported version, the first 3 outline levels will become
headlines, defining a general document structure.  Additional levels
will be exported as itemized lists.  If you want that transition to
occur at a different level, specify it with a prefix argument.  For
example,

     C-2 C-c C-x b

creates two levels of headings and does the rest as items.

   If you want to include HTML tags which should be interpreted as such,
mark them with `@' as in `@<b>bold text@</b>'.  Plain `<' and `>' are
always transformed to `&lt;' and `&gt;' in HTML export.

   Internal links (*note Internal links::) will continue to work in HTML
files only if they match a dedicated `<<target>>'.  Automatic links
created by radio targets (*note Radio targets::) will also work in the
HTML file.  Links to external files will still work if the HTML file is
in the same directory as the Org-mode file.  Links to other `.org'
files will be translated into HTML links under the assumption that an
HTML version also exists of the linked file.  For information related to
linking files while publishing them to a publishing directory see *Note
Publishing links::.

   You can also give style information for the exported file.  The HTML
exporter assigns the following CSS classes to appropriate parts of the
document - your style specifications may change these:
     .todo           TODO keywords
     .done           the DONE keyword
     .timestamp      time stamp
     .timestamp-kwd  keyword associated with a time stamp, like SCHEDULED
     .tag            tag in a headline
     .target         target for links

   The default style specification can be configured through the option
`org-export-html-style'.  If you want to use a file-local style, you
may use file variables, best wrapped into a COMMENT section at the end
of the outline tree.  For example:

     * COMMENT HTML style specifications

     # Local Variables:
     # org-export-html-style: "   <style type=\"text/css\">
     #       p {font-weight: normal; color: gray; }
     #       h1 {color: black; }
     #   </style>"
     # End:

   Remember to execute `M-x normal-mode' after changing this to make
the new style visible to Emacs.  This command restarts org-mode for the
current buffer and forces Emacs to re-evaluate the local variables
section in the buffer.

10.3 XOXO export
================

Org-mode contains an exporter that produces XOXO-style output.
Currently, this exporter only handles the general outline structure and
does not interpret any additional Org-mode features.

`C-c C-x C-x'
     Export as XOXO file `myfile.html'.  

`C-c C-x v x'
     Export only the visible part of the document.

\x1f
File: org,  Node: iCalendar export,  Next: Text interpretation,  Prev: XOXO export,  Up: Exporting

10.4 iCalendar export
=====================

Some people like to use Org-mode for keeping track of projects, but
still prefer a standard calendar application for anniversaries and
appointments.  In this case it can be useful to have deadlines and
other time-stamped items in Org-mode files show up in the calendar
application.  Org-mode can export calendar information in the standard
iCalendar format.

`C-c C-x i'
     Create iCalendar entries for the current file and store them in
     the same directory, using a file extension `.ics'.  

`C-c C-x C-i'
     Like `C-c C-x i', but do this for all files in `org-agenda-files'.
     For each of these files, a separate iCalendar file will be
     written.  

`C-c C-x c'
     Create a single large iCalendar file from all files in
     `org-agenda-files' and write it to the file given by
     `org-combined-agenda-icalendar-file'.

   How this calendar is best read and updated, depends on the
application you are using.  For example, when using iCal under Apple
MacOS X, you could create a new calendar `OrgMode' (the default name
for the calendar created by `C-c C-x c', see the variables
`org-icalendar-combined-name' and
`org-combined-agenda-icalendar-file').  Then set Org-mode to overwrite
the corresponding file `~/Library/Calendars/OrgMode.ics'.  You may even
use AppleScript to make iCal re-read the calendar files each time a new
version of `OrgMode.ics' is produced.  Here is the setup needed for
this:

     (setq org-combined-agenda-icalendar-file
         "~/Library/Calendars/OrgMode.ics")
     (add-hook 'org-after-save-iCalendar-file-hook
      (lambda ()
       (shell-command
        "osascript -e 'tell application \"iCal\" to reload calendars'")))

10.5 Text interpretation by the exporter
========================================

The exporter backends interpret additional structure in the Org-mode
file in order to produce better output.

* Comment lines::               Some lines will not be exported
* Enhancing text::              Subscripts, symbols and more

10.5.1 Comment lines
--------------------

Lines starting with `#' in column zero are treated as comments and will
never be exported.  Also entire subtrees starting with the word
`COMMENT' will never be exported.  Finally, any text before the first
headline will not be exported either.

`C-c ;'
     Toggle the COMMENT keyword at the beginning of an entry.

\x1f
File: org,  Node: Enhancing text,  Next: Export options,  Prev: Comment lines,  Up: Text interpretation

10.5.2 Enhancing text for export
--------------------------------

Some of the export backends of Org-mode allow for sophisticated text
formatting, this is true in particular for the HTML backend.  Org-mode
has a number of typing conventions that allow to produce a richly
formatted output.

   * Plain lists `-', `*' or `+' as bullet, or with `1.' or `2)' as
     enumerator will be recognized and transformed if the backend
     supports lists.  See *Note Plain lists::.

   * You can make words *bold*, /italic/, _underlined_, `=code=', and
     `+strikethrough+'.

   * Many TeX macros and entire LaTeX fragments are converted into HTML
     entities or images (*note Embedded LaTeX::).

   * Tables are transformed into native tables under the exporter, if
     the export backend supports this. Data fields before the first
     horizontal separator line will be formatted as table header fields.

   * If a headline starts with the word `QUOTE', the text below the
     headline will be typeset as fixed-width, to allow quoting of
     computer codes etc.  Lines starting with `:' are also typeset in
     fixed-width font.
    `C-c :'
          Toggle fixed-width for entry (QUOTE) or region, see below.

   * A double backslash _at the end of a line_ enforces a line break at
     this position.

   If these conversions conflict with your habits of typing ASCII text,
they can all be turned off with corresponding variables (see the
customization group `org-export-general', and the following section
which explains how to set export options with special lines in a buffer.

\x1f
File: org,  Node: Export options,  Prev: Enhancing text,  Up: Text interpretation

10.5.3 Export options
---------------------

The exporter recognizes special lines in the buffer which provide
additional information.  These lines may be put anywhere in the file.
The whole set of lines can be inserted into the buffer with `C-c C-x
t'.  For individual lines, a good way to make sure the keyword is
correct is to type `#+' and then use `M-<TAB>' completion (*note
Completion::).

`C-c C-x t'
     Insert template with export options, see example below.

     #+TITLE:     the title to be shown (default is the buffer name)
     #+AUTHOR:    the author (default taken from `user-full-name')
     #+EMAIL:     his/her email address (default from `user-mail-address')
     #+LANGUAGE:  language for HTML, e.g. `en' (`org-export-default-language')
     #+TEXT:      Some descriptive text to be inserted at the beginning.
     #+TEXT:      Several lines may be given.
     #+OPTIONS:   H:2 num:t toc:t \n:nil @:t ::t |:t ^:t *:nil TeX:t LaTeX:t

The OPTIONS line is a compact form to specify export settings.  Here
you can: 
     H:      set the number of headline levels for export
     num:    turn on/off section-numbers
     toc:    turn on/off table of contents
     \n:     turn on/off linebreak-preservation
     @:      turn on/off quoted HTML tags
     ::      turn on/off fixed-width sections
     |:      turn on/off tables
     ^:      turn on/off TeX-like syntax for sub- and superscripts.
     *:      turn on/off emphasized text (bold, italic, underlined)
     TeX:    turn on/off simple TeX macros in plain text

11 Publishing
*************

Org-mode includes(1) a publishing management system that allows you to
configure automatic HTML conversion of _projects_ composed of
interlinked org files.  This system is called _org-publish_.  You can
also configure org-publish to automatically upload your exported HTML
pages and related attachments, such as images and source code files, to
a web server.  Org-publish turns org-mode into a web-site authoring
tool.

   Org-publish has been contributed to Org-mode by David O'Toole.

\x1f
File: org,  Node: Configuration,  Next: Sample configuration,  Prev: Publishing,  Up: Publishing

11.1 Configuration
==================

Publishing needs significant configuration to specify files, destination
and many other properties of a project.

* Menu:

* Project alist::               The central configuration variable
* Sources and destinations::    From here to there
* Selecting files::             What files are part of the project?
* Publishing action::           Setting the function doing the publishing
* Publishing options::          Tweaking HTML export

* Project page index::          Publishing a list of project files

\x1f
File: org,  Node: Project alist,  Next: Sources and destinations,  Prev: Configuration,  Up: Configuration

11.1.1 The variable `org-publish-project-alist'
-----------------------------------------------

Org-publish is configured almost entirely through setting the value of
one variable, called `org-publish-project-alist'.  Each element of the
list configures one project, and may be in one of the two following
forms:

     ("project-name"  :property value :property value ...)

     or

     ("project-name"  :components ("project-name" "project-name" ...))

   In both cases, projects are configured by specifying property values.
A project defines the set of files that will be published, as well as
the publishing configuration to use when publishing those files.  When
a project takes the second form listed above, the individual members of
the "components" property are taken to be components of the project,
which group together files requiring different publishing options. When
you publish such a "meta-project" all the components will also publish.

\x1f
File: org,  Node: Sources and destinations,  Next: Selecting files,  Prev: Project alist,  Up: Configuration

11.1.2 Sources and destinations for files
-----------------------------------------

Most properties are optional, but some should always be set. In
particular, org-publish needs to know where to look for source files,
and where to put published files.

`:base-directory'      Directory containing publishing source files
`:publishing-directory'Directory (possibly remote) where output files
                       will be published.

\x1f
File: org,  Node: Selecting files,  Next: Publishing action,  Prev: Sources and destinations,  Up: Configuration

11.1.3 Selecting files
----------------------

By default, all files with extension `.org' in the base directory are
considered part of the project.  This can be modified by setting the
properties
`:base-extension'  Extension (without the dot!) of source files.  This
                   actually is a regular expression.
`:exclude'         Regular expression to match file names that should
                   not be published, even though they have been selected
                   on the basis of their extension.
`:include'         List of files to be included regardless of
                   `:base-extension' and `:exclude'.

\x1f
File: org,  Node: Publishing action,  Next: Publishing options,  Prev: Selecting files,  Up: Configuration

11.1.4 Publishing Action
------------------------

Publishing means that a file is copied to the destination directory and
possibly transformed in the process.  The default transformation is to
export Org-mode files as HTML files, and this is done by the function
`org-publish-org-to-html' which calls the HTML exporter (*note HTML
export::).  Other files like images only need to be copied to the
publishing destination.  For non-Org-mode files, you need to specify
the publishing function.

`:publishing-function' Function executing the publication of a file.

   The function must accept two arguments: a property list containing at
least a `:publishing-directory' property, and the name of the file to
be published.  It should take the specified file, make the necessary
transformation (if any) and place the result into the destination
folder.  You can write your own publishing function, but `org-publish'
provides one for attachments (files that only need to be copied):
`org-publish-attachment'.

11.1.5 Options for the HTML exporter
------------------------------------

The property list can be used to set many export options for the HTML
exporter.  In most cases, these properties correspond to user variables
in Org-mode.  The table below lists these properties along with the
variable they belong to.  See the documentation string for the
respective variable for details.

`:language'            `org-export-default-language'

`:tables'              `org-export-with-tables'
`:table-auto-headline' `org-export-highlight-first-table-line'
`:style'               `org-export-html-style'
`:convert-org-links'   `org-export-html-link-org-files-as-html'
`:inline-images'       `org-export-html-inline-images'
`:expand-quoted-html'  `org-export-html-expand'
`:timestamp'           `org-export-html-with-timestamp'
`:publishing-directory'`org-export-publishing-directory'
`:preamble'            `org-export-html-preamble'
`:postamble'           `org-export-html-postamble'
`:auto-preamble'       `org-export-html-auto-preamble'
`:auto-postamble'      `org-export-html-auto-postamble'
`:author'              `user-full-name'
`:email'               `user-mail-address'

   When a property is given a value in org-publish-project-alist, its
setting overrides the value of the corresponding user variable (if any)
during publishing.  options set within a file (*note Export options::),
however, override everything.

\x1f
File: org,  Node: Publishing links,  Next: Project page index,  Prev: Publishing options,  Up: Configuration

11.1.6 Links between published files
------------------------------------

To create a link from one Org-mode file to another, you would use
something like `[[file:foo.org][The foo]]' or simply `file:foo.org.'
(*note Hyperlinks::).  Upon publishing this link becomes a link to
`foo.html'.  In this way, you can interlink the pages of your "org web"
project and the links will work as expected when you publish them to
HTML.

   You may also link to related files, such as images. Provided you are
careful with relative pathnames, and provided you have also configured
org-publish to upload the related files, these links will work too.
*Note Complex example:: for an example of this usage.

   Sometime an Org-mode file to be published may contain links that are
only valid in your production environment, but not in the publishing
location.  In this case, use the property

`:link-validation-function'   Function to validate links

to define a function for checking link validity.  This function must
accept two arguments, the file name and a directory relative to which
the file name is interpreted in the production environment.  If this
function returns `nil', then the HTML generator will only insert a

11.1.7 Project page index
-------------------------

The following properties may be used to control publishing of an index
of files or summary page for a given project.

`:auto-index'      When non-nil, publish an index during
                   org-publish-current-project or org-publish-all.
`:index-filename'  Filename for output of index. Defaults to `index.org'
                   (which becomes `index.html').
`:index-title'     Title of index page. Defaults to name of file.
`:index-function'  Plugin function to use for generation of index.
                   Defaults to `org-publish-org-index', which generates
                   a plain list of links to all files in the project.

=========================

Below we provide two example configurations.  The first one is a simple
project publishing only a set of Org-mode files.  The second example is
more complex, with a multi-component project.

11.2.1 Example: simple publishing configuration
-----------------------------------------------

This example publishes a set of Org-mode files to the `public_html'
directory on the local machine.

     (setq org-publish-project-alist
           '(("org"
              :base-directory "~/org/"
              :publishing-directory "~/public_html"
              :section-numbers nil
              :table-of-contents nil
              :style "<link rel=stylesheet
                     href=\"../other/mystyle.css\"
                     type=\"text/css\">")))

\x1f
File: org,  Node: Complex example,  Prev: Simple example,  Up: Sample configuration

11.2.2 Example: complex publishing configuration
------------------------------------------------

This more complicated example publishes an entire website, including
org files converted to HTML, image files, emacs lisp source code, and
stylesheets. The publishing-directory is remote and private files are
excluded.

   To ensure that links are preserved, care should be taken to replicate
your directory structure on the web server, and to use relative file
paths. For example, if your org files are kept in `~/org' and your
publishable images in `~/images', you'd link to an image with
     file:../images/myimage.png
   On the web server, the relative path to the image should be the
same. You can accomplish this by setting up an "images" folder in the
right place on the webserver, and publishing images to it.

     (setq org-publish-project-alist
           '(("orgfiles"
               :base-directory "~/org/"
               :base-extension "org"
               :publishing-directory "/ssh:user@host:~/html/notebook/"
               :publishing-function org-publish-org-to-html
               :exclude "PrivatePage.org"   ;; regexp
               :headline-levels 3
               :section-numbers nil
               :table-of-contents nil
               :style "<link rel=stylesheet
                       href=\"../other/mystyle.css\" type=\"text/css\">"
               :auto-preamble t
               :auto-postamble nil)

              ("images"
               :base-directory "~/images/"
               :base-extension "jpg\\|gif\\|png"
               :publishing-directory "/ssh:user@host:~/html/images/"
               :publishing-function org-publish-attachment)

              ("other"
               :base-directory "~/other/"
               :base-extension "css\\|el"
               :publishing-directory "/ssh:user@host:~/html/other/"
               :publishing-function org-publish-attachment)
              ("website" :components ("orgfiles" "images" "other"))))

File: org,  Node: Triggering publication,  Prev: Sample configuration,  Up: Publishing

11.3 Triggering publication
===========================

Once org-publish is properly configured, you can publish with the
following functions:

`C-c C-e c'
     Prompts for a specific project to publish.

`C-c C-e p'
     Publishes the project the current file is part of.

`C-c C-e f'
     Publishes only the current file.

`C-c C-e a'
     Publish all projects.

   Org uses timestamps to track when a file has changed. The above
functions normally only publish changed files. You can override this and
force publishing of all files by giving a prefix argument.

12.1 Completion
===============

Org-mode supports in-buffer completion.  This type of completion does
not make use of the minibuffer.  You simply type a few letters into the
buffer and use the key to complete text right there.

`M-<TAB>'
     Complete word at point
        * At the beginning of a headline, complete TODO keywords.

        * After `\', complete TeX symbols supported by the exporter.

        * After `*', complete CamelCase versions of all headlines in the
          buffer.

        * After `:', complete tags used elsewhere in the buffer.

        * After `#+', complete the special keywords like `TYP_TODO' or
          `OPTIONS' which set file-specific options for Org-mode.  When
          the option keyword is already complete, pressing `M-<TAB>'
          again will insert example settings for this keyword.

        * Elsewhere, complete dictionary words using ispell.

12.2 Customization
==================

There are more than 100 variables that can be used to customize
Org-mode.  For the sake of compactness of the manual, we are not
describing the variables here.  A structured overview of customization
variables is available with `M-x org-customize'.  Or select `Browse Org
Group' from the `Org->Customization' menu.  Many settings can also be
activated on a per-file basis, by putting special lines into the buffer
(*note In-buffer settings::).

\x1f
File: org,  Node: In-buffer settings,  Next: The very busy C-c C-c key,  Prev: Customization,  Up: Miscellaneous

12.3 Summary of in-buffer settings
==================================

Org-mode uses special lines in the buffer to define settings on a
per-file basis.  These lines start with a `#+' followed by a keyword, a
colon, and then individual words defining a setting.  Several setting
words can be in the same line, but you can also have multiple lines for
the keyword.  While these settings are described throughout the manual,
here is a summary.  After changing any of those lines in the buffer,
press `C-c C-c' with the cursor still in the line to activate the
changes immediately.  Otherwise they become effective only when the
file is visited again in a new Emacs session.

`#+STARTUP:'
     This line sets options to be used at startup of org-mode, when an
     Org-mode file is being visited.  The first set of options deals
     with the initial visibility of the outline tree.  The
     corresponding variable for global default settings is
     `org-startup-folded', with a default value `t', which means
     `overview'.
          overview   top-level headlines only
          content    all headlines
          showall    no folding at all, show everything
     Then there are options for aligning tables upon visiting a file.
     This is useful in files containing narrowed table columns.  The
     corresponding variable is `org-startup-align-all-tables', with a
     default value `nil'.
          align      align all tables
          noalign    don't align tables on startup
     Logging when a TODO item is marked DONE (variable `org-log-done')
     can be configured using these options.
          logging    record a timestamp when an item is marked DONE
          nologging  don't record when items are marked DONE
     Here are the options for hiding leading stars in outline headings.
     The corresponding variables are `org-hide-leading-stars' and
     `org-odd-levels-only', both with a default setting `nil' (meaning
     `showstars' and `oddeven').
          hidestars  make all but one of the stars starting a headline invisible.
          showstars  show all stars starting a headline
          odd        allow only odd outline levels (1,3,...)
          oddeven    allow all outline levels

`#+SEQ_TODO:   #+TYP_TODO:'
     These lines set the TODO keywords and their interpretation in the
     current file.  The corresponding variables are `org-todo-keywords'
     and `org-todo-interpretation'.

`#+TAGS:  TAG1(c1) TAG2(c2)'
     These lines (several such lines are allowed) specify the legal
     tags in this file, and (potentially) the corresponding _fast tag
     selection_ keys.  The corresponding variable is `org-tag-alist'.

`#+CATEGORY:'
     This line sets the category for the agenda file.  The category
     applies for all subsequent lines until the next `#+CATEGORY' line,
     or the end of the file.

`#+TBLFM:'
     This line contains the formulas for the table directly above the
     line.

`#+TITLE:, #+AUTHOR:, #+EMAIL:, #+LANGUAGE:, #+TEXT:, #+OPTIONS:'
     These lines provide settings for exporting files.  For more
     details see *Note Export options::.

12.4 The very busy C-c C-c key
==============================

The key `C-c C-c' has many purposes in org-mode, which are all
mentioned scattered throughout this manual.  One specific function of
this key is to add _tags_ to a headline (*note Tags::).  In many other
circumstances it means something like _Hey Org-mode, look here and
update according to what you see here_.  Here is a summary of what this
means in different contexts.

   - If there are highlights in the buffer from the creation of a sparse
     tree, or from clock display, remove these highlights.

   - If the cursor is in one of the special `#+KEYWORD' lines, this
     triggers scanning the buffer for these lines and updating the
     information.

   - If the cursor is inside a table, realign the table.  This command
     works even if the automatic table editor has been turned off.

   - If the cursor is on a `#+TBLFM' line, re-apply the formulas to the
     entire table.

   - If the cursor is inside a table created by the `table.el' package,
     activate that table.

   - If the current buffer is a remember buffer, close note and file it.
     with a prefix argument, file it without further interaction to the
     default location.

   - If the cursor is on a `<<<target>>>', update radio targets and
     corresponding links in this buffer.

   - If the cursor is in a plain list item with a checkbox, toggle the
     status of the checkbox.

   - If the cursor is on a numbered item in a plain list, renumber the
     ordered list.

\x1f
File: org,  Node: Clean view,  Next: TTY keys,  Prev: The very busy C-c C-c key,  Up: Miscellaneous

12.5 A cleaner outline view
===========================

Some people find it noisy and distracting that the Org-mode headlines
are starting with a potentially large number of stars.  For example the
tree from *Note Headlines:::

     * Top level headline
     ** Second level
     *** 3rd level
         some text
     *** 3rd level
         more text
     * Another top level headline

Unfortunately this is deeply ingrained into the code of Org-mode and
cannot be easily changed.  You can, however, modify the display in such
a way that all leading stars become invisible and the outline more easy
to read.  To do this, customize the variable `org-hide-leading-stars'
like this:

     (setq org-hide-leading-stars t)

or change this on a per-file basis with one of the lines (anywhere in
the buffer)

     #+STARTUP: showstars
     #+STARTUP: hidestars

Press `C-c C-c' with the cursor in a `STARTUP' line to activate the
modifications.

   With stars hidden, the tree becomes:

     * Top level headline
      * Second level
       * 3rd level
         some text
       * 3rd level
         more text
     * Another top level headline

Note that the leading stars are not truly replaced by whitespace, they
are only fontified with the face `org-hide' that uses the background
color as font color.  If are are not using either white or black
background, you may have to customize this face to get the wanted
effect.  Another possibility is to set this font such that the extra
stars are almost invisible, for example using the color `grey90' on a
white background.

   Things become cleaner still if you skip all the even levels and use
only odd levels 1, 3, 5..., effectively adding two stars to go from one
outline level to the next:

     * Top level headline
       * Second level
         * 3rd level
           some text
         * 3rd level
           more text
     * Another top level headline

In order to make the structure editing and export commands handle this
convention correctly, use

     (setq org-odd-levels-only t)

or set this on a per-file basis with one of the following lines (don't
forget to press `C-c C-c' with the cursor in the startup line to
activate changes immediately).

     #+STARTUP: odd
     #+STARTUP: oddeven

   You can convert an Org-mode file from single-star-per-level to the
double-star-per-level convention with `M-x org-convert-to-odd-levels
RET' in that file.  The reverse operation is `M-x
org-convert-to-oddeven-levels'.

File: org,  Node: TTY keys,  Next: Interaction,  Prev: Clean view,  Up: Miscellaneous

12.6 Using org-mode on a tty
============================

Org-mode uses a number of keys that are not accessible on a tty.  This
applies to most special keys like cursor keys, <TAB> and <RET>, when
these are combined with modifier keys like <Meta> and/or <Shift>.
Org-mode uses these bindings because it needs to provide keys for a
large number of commands, and because these keys appeared particularly
easy to remember.  In order to still be able to access the core
functionality of Org-mode on a tty, alternative bindings are provided.
Here is a complete list of these bindings, which are obviously more
cumbersome to use.  Note that sometimes a work-around can be better.
For example changing a time stamp is really only fun with `S-<cursor>'
keys.  On a tty you would rather use `C-c .'  to re-insert the
timestamp.

Default     Alternative 1  Alternative 2
`S-<TAB>'   `C-u <TAB>'    
`M-<left>'  `C-c C-x l'    `<Esc> <left>'
`M-S-<left>'`C-c C-x L'    
`M-<right>' `C-c C-x r'    `<Esc>
                           <right>'
`M-S-<right>'`C-c C-x R'    
`M-<up>'    `C-c C-x u'    `<Esc> <up>'
`M-S-<up>'  `C-c C-x U'    
`M-<down>'  `C-c C-x d'    `<Esc> <down>'
`M-S-<down>'`C-c C-x D'    
`S-<RET>'   `C-c C-x c'    
`M-<RET>'   `C-c C-x m'    `<Esc> <RET>'
`M-S-<RET>' `C-c C-x M'    
`S-<left>'  `C-c C-x       
            <left>'        
`S-<right>' `C-c C-x       
            <right>'       
`S-<up>'    `C-c C-x       
            <up>'          
`S-<down>'  `C-c C-x       
            <down>'

12.7 Interaction with other packages
====================================

with other code out there.

12.7.1 Packages that Org-mode cooperates with
---------------------------------------------

`calc.el' by Dave Gillespie
     Org-mode uses the calc package for implementing spreadsheet
     functionality in its tables (*note Table calculations::).
     Org-modes checks for the availability of calc by looking for the
     function `calc-eval' which should be autoloaded in your setup if
     calc has been installed properly.  As of Emacs 22, calc is part of
     the Emacs distribution.  Another possibility for interaction
     between the two packages is using calc for embedded calculations.
     *Note Embedded Mode: (calc)Embedded Mode.  

`constants.el' by Carsten Dominik
     In a table formula (*note Table calculations::), it is possible to
     use names for natural constants or units.  Instead of defining
     your own constants in the variable `org-table-formula-constants',
     install the `constants' package which defines a large number of
     constants and units, and lets you use unit prefixes like `M' for
     `Mega' etc.  You will need version 2.0 of this package, available
     at `http://www.astro.uva.nl/~dominik/Tools'. Org-mode checks for
     the function `constants-get', which has to be autoloaded in your
     setup.  See the installation instructions in the file
     `constants.el'.

`cdlatex.el' by Carsten Dominik
     Org-mode can make use of the cdlatex package to efficiently enter
     LaTeX fragments into Org-mode files.  `cdlatex.el' is not part of
     Emacs, find it on the web.

`remember.el' by John Wiegley
     Org mode cooperates with remember, see *Note Remember::.
     `Remember.el' is not part of Emacs, find it on the web.  

`table.el' by Takaaki Ota
     Org mode cooperates with table.el, see *Note table.el::.
     `table.el' is part of Emacs 22.

\x1f
File: org,  Node: Conflicts,  Prev: Cooperation,  Up: Interaction

12.7.2 Packages that lead to conflicts with Org-mode
----------------------------------------------------

`allout.el' by Ken Manheimer
     Startup of Org-mode may fail with the error message
     `(wrong-type-argument keymapp nil)' when there is an outdated
     version `allout.el' on the load path, for example the version
     distributed with Emacs 21.x.  Upgrade to Emacs 22 and this problem
     will disappear.  If for some reason you cannot do this, make sure
     that org.el is loaded _before_ `allout.el', for example by putting
     `(require 'org)' early enough into your `.emacs' file.

`CUA.el' by Kim. F. Storm
     Keybindings in Org-mode conflict with the `S-<cursor>' keys used
     by CUA-mode (as well as pc-select-mode and s-region-mode) to
     select and extend the region.  If you want to use one of these
     packages along with Org-mode, configure the variable
     `org-CUA-compatible'.  When set, Org-mode will move the following
     keybindings in org-mode files, and in the agenda buffer (but not
     during date selection).

          S-UP    -> M-p             S-DOWN  -> M-n
          S-LEFT  -> M--             S-RIGHT -> M-+
          S-RET   -> C-S-RET

     Yes, these are unfortunately more difficult to remember.  If you
     want to have other replacement keys, look at the variable
     `org-disputed-keys'.

`windmove.el' by Hovav Shacham
     Also this package uses the `S-<cursor>' keys, so everything written
     in the paragraph above about CUA mode also applies here.

12.8 Bugs
=========

Here is a list of things that should work differently, but which I have
found too hard to fix.

   * If a table field starts with a link, and if the corresponding table
     column is narrowed (*note Narrow columns::) to a width too small to
     display the link, the field would look entirely empty even though
     it is not.  To prevent this, Org-mode throws an error.  The
     work-around is to make the column wide enough to fit the link, or
     to add some text (at least 2 characters) before the link in the
     same field.

   * Narrowing table columns does not work on XEmacs, because the
     `format' function does not transport text properties.

   * Text in an entry protected with the `QUOTE' keyword should not
     autowrap.

   * When the application called by `C-c C-o' to open a file link fails
     (for example because the application does not exist or refuses to
     open the file), it does so silently.  No error message is
     displayed.

   * The remote-editing commands in the agenda buffer cannot be undone
     with `undo' called from within the agenda buffer.  But you can go
     to the corresponding buffer (using <TAB> or <RET> and execute
     `undo' there.

   * Recalculating a table line applies the formulas from left to right.
     If a formula uses _calculated_ fields further down the row,
     multiple recalculation may be needed to get all fields consistent.

   * A single letter cannot be made bold, for example `*a*'.

   * The exporters work well, but could be made more efficient.

A.1 Third-party extensions for Org-mode
=======================================

The following extensions for Org-mode have been written by other people:

`org-mouse.el' by Piotr Zielinski
     This package implements extended mouse functionality for Org-mode.
     It allows you to cycle visibility and to edit the document
     structure with the mouse.  Best of all, it provides a
     context-sensitive menu on <mouse-3> that changes depending on the
     context of a mouse-click.  `org-mouse.el' is freely available at
     `http://www.cl.cam.ac.uk/~pz215/files/org-mouse.el'.  

`org-publish.el' by David O'Toole
     This package provides facilities for publishing related sets of
     Org-mode files together with linked files like images as a
     webpages.  It is highly configurable and can be used for other
     publishing purposes as well.  As of Org-mode version 4.30,
     `org-publish.el' is part of the Org-mode distribution.  It is not
     yet part of Emacs, however, a delay caused by the preparations for
     the 22.1 release.  In the mean time, `org-publish.el' can be
     downloaded from David's site:

A.2 Dynamic blocks
==================

Org-mode documents can contain _dynamic blocks_.  These are specially
marked regions that are updates by some user-written function.  A good
example for such a block is the clock table inserted by the command
`C-c C-x C-r' (*note Clocking work time::).

   Dynamic block are enclosed by a BEGIN-END structure that assigns a
name to the block and can also specify parameters for the function
producing the content of the block.

     #+BEGIN: myblock :parameter1 value1 :parameter2 value2 .....

     #+END:

   Dynamic blocks are updated with the following commands

`C-c C-x C-u'
     Update dynamic block at point.  

`C-u C-c C-x C-u'
     Update all dynamic blocks in the current file.

   Updating a dynamic block means to remove all the text between BEGIN
and END, parse the BEGIN line for parameters and then call the specific
writer function for this block to insert the new content.  For a block
with name `myblock', the writer function is `org-dblock-write:myblock'
with as only parameter a property list with the parameters given in the
begin line.  Here is a trivial example of a block that keeps track of
when the block update function was last run:

     #+BEGIN: block-update-time :format "on %m/%d/%Y at %H:%M"

     #+END:

The corresponding block writer function could look like this:

     (defun org-dblock-write:date-and-time (params)
        (let ((fmt (or (plist-get params :format) "%d. %m. %Y")))
          (insert "Last block update at: "
             (format-time-string fmt (current-time)))))

   If you want to make sure that all dynamic blocks are always
up-to-date, you could add the function `org-update-all-dblocks' to a
hook, for example `before-save-hook'.  `org-update-all-dblocks' is
written in a way that is does nothing in buffers that are not in
Org-mode.

Appendix B History and Acknowledgments
**************************************

The beginnings of Org-mode go back to 2003.  It was borne out of
frustration over the user interface of the emacs outline-mode.  All I
wanted was to make working with an outline tree possible without having
to remember more than 10 commands just for hiding and unhiding parts of
the outline tree, and to allow to restructure a tree easily.  Visibility
cycling and structure editing were originally implemented in the package
`outline-magic.el', but quickly moved to the more general `org.el'.
TODO entries, basic time stamps, and table support were added next, and
highlight the two main goals that Org-mode still has today:  To create
a new, outline-based, plain text mode with innovative and intuitive
editing features, and to incorporate project planning functionality
directly into a notes file.

   Since the first release, hundreds of emails to me or on
`emacs-orgmode@gnu.org' have provided a constant stream of bug reports,
feedback, new ideas, and sometimes even patches and add-on code.  Many
thanks to everyone who has helped to improve this package.  I am trying
to keep here a list of the people who had significant influence in
shaping one or more aspects of Org-mode.  The list may not be complete,
if I have forgotten someone, please accept my apologies and let me know.

   * Thomas Baumann contributed the code for links to the MH-E email
     system.

   * Alex Bochannek provided a patch for rounding time stamps.

   * Charles Cave's suggestion sparked the implementation of templates
     for Remember.

   * Pavel Chalmoviansky influenced the agenda treatment of items with
     specified time.

   * Gregory Chernov patched support for lisp forms into table
     calculations and improved XEmacs compatibility, in particular by
     porting `nouline.el' to XEmacs.

   * Sacha Chua suggested to copy some linking code from Planner.

   * Kees Dullemond inspired the use of narrowed tabled columns.

   * Christian Egli converted the documentation into TeXInfo format,
     patched CSS formatting into the HTML exporter, and inspired the
     agenda.

   * Nic Ferrier contributed mailcap and XOXO support.

   * Niels Giessen had the idea to automatically archive DONE trees.

   * Bastien Guerry provoded extensive feedback.

   * Kai Grossjohann pointed out key-binding conflicts caused by
     Org-mode.

   * Leon Liu asked for embedded LaTeX and tested it.

   * Stefan Monnier provided a patch to keep the Emacs-Lisp compiler
     happy.

   * Todd Neal provided patches for links to Info files and elisp forms.

   * Tim O'Callaghan suggested in-file links, search options for general
     file links, and TAGS.

   * Oliver Oppitz suggested multi-state TODO items.

   * Scott Otterson sparked the introduction of descriptive text for
     links, among other things.

   * Pete Phillips helped the development of the TAGS feature.

   * T.V. Raman reported bugs and suggested improvements.

   * Matthias Rempe (Oelde) provided ideas, Windows support, and quality
     control.

   * Kevin Rogers contributed code to access VM files on remote hosts.

   * Frank Ruell solved the mystery of the `keymapp nil' bug, a
     conflict with `allout.el'.

   * Philip Rooke created the Org-mode reference card and provided lots
     of feedback.

   * Christian Schlauer proposed angular brackets around links, among
     other things.

   * Linking to VM/BBDB/GNUS was inspired by Tom Shannon's
     `organizer-mode.el'.

   * Daniel Sinder came up with the idea of internal archiving by
     locking subtrees.

   * David O'Toole wrote `org-publish.el' and drafted the manual
     chapter about publishing.

   * Ju"rgen Vollmer contributed code generating the table of contents
     in HTML output.

   * Chris Wallace provided a patch implementing the `QUOTE' keyword.

   * David Wainberg suggested archiving, and improvements to the linking
     system.

   * John Wiegley wrote `emacs-wiki.el' and `planner.el'.  The
     development of Org-mode was fully independent, and both systems are
     really different beasts in their basic ideas and implementation
     details.  I later looked at John's code, however, and learned from
     his implementation of (i) links where the link itself is hidden
     and only a description is shown, and (ii) popping up a calendar to
     select a date.

   * Carsten Wimmer suggested some changes and helped fix a bug in
     linking to GNUS.

   * Roland Winkler requested additional keybindings to make Org-mode
     work on a tty.

   * Piotr Zielinski wrote `org-mouse.el' and showed how to follow
     links with mouse-1.
