979 \(optionally) its subdirectories, in the format of `ls -lR'.
980 Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
981 \"Editing\" means that you can run shell commands on files, visit,
982 compress, load or byte-compile them, change their file attributes
983 and insert subdirectories into the same buffer. You can \"mark\"
984 files for later commands or \"flag\" them for deletion, either file
985 by file or all files matching certain criteria.
986 You can move using the usual cursor motion commands.\\<dired-mode-map>
987 Letters no longer insert themselves. Digits are prefix arguments.
988 Instead, type \\[dired-flag-file-deletion] to flag a file for Deletion.
989 Type \\[dired-mark] to Mark a file or subdirectory for later commands.
990 Most commands operate on the marked files and use the current file
991 if no files are marked. Use a numeric prefix argument to operate on
992 the next ARG (or previous -ARG if ARG<0) files, or just `1'
993 to operate on the current file only. Prefix arguments override marks.
994 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
995 to see why something went wrong.
996 Type \\[dired-unmark] to Unmark a file or all files of a subdirectory.
997 Type \\[dired-unmark-backward] to back up one line and unflag.
998 Type \\[dired-do-flagged-delete] to eXecute the deletions requested.
999 Type \\[dired-advertised-find-file] to Find the current line's file
1000 (or dired it in another buffer, if it is a directory).
1001 Type \\[dired-find-file-other-window] to find file or dired directory in Other window.
1002 Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1003 Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1004 Type \\[dired-do-copy] to Copy files.
1005 Type \\[dired-sort-toggle-or-edit] to toggle sorting by name/date or change the `ls' switches.
1006 Type \\[revert-buffer] to read all currently expanded directories again.
1007 This retains all marks and hides subdirs again that were hidden before.
1008 SPC and DEL can be used to move down and up by lines.
1010 If dired ever gets confused, you can either type \\[revert-buffer] \
1011 to read the
1012 directories again, type \\[dired-do-redisplay] \
1013 to relist a single or the marked files or a
1014 subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
1015 again for the directory tree.
