1795 Mode for \"editing\" directory listings.
1796 In Dired, you are \"editing\" a list of the files in a directory and
1797 \(optionally) its subdirectories, in the format of `ls -lR'.
1798 Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
1799 \"Editing\" means that you can run shell commands on files, visit,
1800 compress, load or byte-compile them, change their file attributes
1801 and insert subdirectories into the same buffer. You can \"mark\"
1802 files for later commands or \"flag\" them for deletion, either file
1803 by file or all files matching certain criteria.
1804 You can move using the usual cursor motion commands.\\<dired-mode-map>
1805 The buffer is read-only. Digits are prefix arguments.
1806 Type \\[dired-flag-file-deletion] to flag a file `D' for deletion.
1807 Type \\[dired-mark] to Mark a file or subdirectory for later commands.
1808 Most commands operate on the marked files and use the current file
1809 if no files are marked. Use a numeric prefix argument to operate on
1810 the next ARG (or previous -ARG if ARG<0) files, or just `1'
1811 to operate on the current file only. Prefix arguments override marks.
1812 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
1813 to see why something went wrong.
1814 Type \\[dired-unmark] to Unmark a file or all files of an inserted subdirectory.
1815 Type \\[dired-unmark-backward] to back up one line and unmark or unflag.
1816 Type \\[dired-do-flagged-delete] to delete (eXecute) the files flagged `D'.
1817 Type \\[dired-find-file] to Find the current line's file
1818 (or dired it in another buffer, if it is a directory).
1819 Type \\[dired-find-file-other-window] to find file or dired directory in Other window.
1820 Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1821 Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1822 Type \\[dired-do-copy] to Copy files.
1823 Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches.
1824 Type \\[revert-buffer] to read all currently expanded directories aGain.
1825 This retains all marks and hides subdirs again that were hidden before.
1826 Use `SPC' and `DEL' to move down and up by lines.
1828 If Dired ever gets confused, you can either type \\[revert-buffer] \
1829 to read the
1830 directories again, type \\[dired-do-redisplay] \
1831 to relist the file at point or the marked files or a
1832 subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
1833 again for the directory tree.
