1644 \(optionally) its subdirectories, in the format of `ls -lR'.
1645 Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
1646\"Editing\" means that you can run shell commands on files, visit,
1647 compress, load or byte-compile them, change their file attributes
1648 and insert subdirectories into the same buffer. You can \"mark\"
1649 files for later commands or \"flag\" them for deletion, either file
1650 by file or all files matching certain criteria.
1651You can move using the usual cursor motion commands.\\<dired-mode-map>
1652Letters no longer insert themselves. Digits are prefix arguments.
1653Instead, type \\[dired-flag-file-deletion] to flag a file for Deletion.
1654Type \\[dired-mark] to Mark a file or subdirectory for later commands.
1655 Most commands operate on the marked files and use the current file
1656 if no files are marked. Use a numeric prefix argument to operate on
1657 the next ARG (or previous -ARG if ARG<0) files, or just `1'
1658 to operate on the current file only. Prefix arguments override marks.
1659 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
1660 to see why something went wrong.
1661Type \\[dired-unmark] to Unmark a file or all files of a subdirectory.
1662Type \\[dired-unmark-backward] to back up one line and unflag.
1663Type \\[dired-do-flagged-delete] to eXecute the deletions requested.
1664Type \\[dired-advertised-find-file] to Find the current line's file
1665 (or dired it in another buffer, if it is a directory).
1666Type \\[dired-find-file-other-window] to find file or dired directory in Other window.
1667Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1668Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1669Type \\[dired-do-copy] to Copy files.
ee680b2b
JB
1670Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches.
1671Type \\[revert-buffer] to read all currently expanded directories aGain.

1672 This retains all marks and hides subdirs again that were hidden before.
1673SPC and DEL can be used to move down and up by lines.
