1744 Mode for \"editing\" directory listings.
1745 In Dired, you are \"editing\" a list of the files in a directory and
1746 \(optionally) its subdirectories, in the format of `ls -lR'.
1747 Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
1748 \"Editing\" means that you can run shell commands on files, visit,
1749 compress, load or byte-compile them, change their file attributes
1750 and insert subdirectories into the same buffer. You can \"mark\"
1751 files for later commands or \"flag\" them for deletion, either file
1752 by file or all files matching certain criteria.
1753 You can move using the usual cursor motion commands.\\<dired-mode-map>
1754 Letters no longer insert themselves. Digits are prefix arguments.
1755 Instead, type \\[dired-flag-file-deletion] to flag a file for Deletion.
1756 Type \\[dired-mark] to Mark a file or subdirectory for later commands.
1757 Most commands operate on the marked files and use the current file
1758 if no files are marked. Use a numeric prefix argument to operate on
1759 the next ARG (or previous -ARG if ARG<0) files, or just `1'
1760 to operate on the current file only. Prefix arguments override marks.
1761 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
1762 to see why something went wrong.
1763 Type \\[dired-unmark] to Unmark a file or all files of a subdirectory.
1764 Type \\[dired-unmark-backward] to back up one line and unflag.
1765 Type \\[dired-do-flagged-delete] to eXecute the deletions requested.
1766 Type \\[dired-find-file] to Find the current line's file
1767 (or dired it in another buffer, if it is a directory).
1768 Type \\[dired-find-file-other-window] to find file or dired directory in Other window.
1769 Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1770 Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1771 Type \\[dired-do-copy] to Copy files.
1772 Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches.
1773 Type \\[revert-buffer] to read all currently expanded directories aGain.
1774 This retains all marks and hides subdirs again that were hidden before.
1775 SPC and DEL can be used to move down and up by lines.
1777 If Dired ever gets confused, you can either type \\[revert-buffer] \
1779 directories again, type \\[dired-do-redisplay] \
1780 to relist a single or the marked files or a
1781 subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
1782 again for the directory tree.
