1639 \(optionally) its subdirectories, in the format of `ls -lR'.
1640 Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
1641\"Editing\" means that you can run shell commands on files, visit,
1642 compress, load or byte-compile them, change their file attributes
1643 and insert subdirectories into the same buffer. You can \"mark\"
1644 files for later commands or \"flag\" them for deletion, either file
1645 by file or all files matching certain criteria.
1646You can move using the usual cursor motion commands.\\<dired-mode-map>
1647Letters no longer insert themselves. Digits are prefix arguments.
1648Instead, type \\[dired-flag-file-deletion] to flag a file for Deletion.
1649Type \\[dired-mark] to Mark a file or subdirectory for later commands.
1650 Most commands operate on the marked files and use the current file
1651 if no files are marked. Use a numeric prefix argument to operate on
1652 the next ARG (or previous -ARG if ARG<0) files, or just `1'
1653 to operate on the current file only. Prefix arguments override marks.
1654 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
1655 to see why something went wrong.
1656Type \\[dired-unmark] to Unmark a file or all files of a subdirectory.
1657Type \\[dired-unmark-backward] to back up one line and unflag.
1658Type \\[dired-do-flagged-delete] to eXecute the deletions requested.
1659Type \\[dired-advertised-find-file] to Find the current line's file
1660 (or dired it in another buffer, if it is a directory).
1661Type \\[dired-find-file-other-window] to find file or dired directory in Other window.
1662Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1663Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1664Type \\[dired-do-copy] to Copy files.
ee680b2b
JB
1665Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches.
1666Type \\[revert-buffer] to read all currently expanded directories aGain.
