1906 Mode for \"editing\" directory listings.
1907 In Dired, you are \"editing\" a list of the files in a directory and
1908 (optionally) its subdirectories, in the format of `ls -lR'.
1909 Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
1910 \"Editing\" means that you can run shell commands on files, visit,
1911 compress, load or byte-compile them, change their file attributes
1912 and insert subdirectories into the same buffer. You can \"mark\"
1913 files for later commands or \"flag\" them for deletion, either file
1914 by file or all files matching certain criteria.
1915 You can move using the usual cursor motion commands.\\<dired-mode-map>
1916 The buffer is read-only. Digits are prefix arguments.
1917 Type \\[dired-flag-file-deletion] to flag a file `D' for deletion.
1918 Type \\[dired-mark] to Mark a file or subdirectory for later commands.
1919 Most commands operate on the marked files and use the current file
1920 if no files are marked. Use a numeric prefix argument to operate on
1921 the next ARG (or previous -ARG if ARG<0) files, or just `1'
1922 to operate on the current file only. Prefix arguments override marks.
1923 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
1924 to see why something went wrong.
1925 Type \\[dired-unmark] to Unmark a file or all files of an inserted subdirectory.
1926 Type \\[dired-unmark-backward] to back up one line and unmark or unflag.
1927 Type \\[dired-do-flagged-delete] to delete (eXpunge) the files flagged `D'.
1928 Type \\[dired-find-file] to Find the current line's file
1929 (or dired it in another buffer, if it is a directory).
1930 Type \\[dired-find-file-other-window] to find file or Dired directory in Other window.
1931 Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1932 Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1933 Type \\[dired-do-copy] to Copy files.
1934 Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches.
1935 Type \\[revert-buffer] to read all currently expanded directories aGain.
1936 This retains all marks and hides subdirs again that were hidden before.
1937 Use `SPC' and `DEL' to move down and up by lines.
1939 If Dired ever gets confused, you can either type \\[revert-buffer] \
1940 to read the
1941 directories again, type \\[dired-do-redisplay] \
1942 to relist the file at point or the marked files or a
1943 subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
1944 again for the directory tree.
1946 Customization variables (rename this buffer and type \\[describe-variable] on each line
1947 for more info):
1949 `dired-listing-switches'
1950 `dired-trivial-filenames'
