1665 Mode for \"editing\" directory listings.
1666 In Dired, you are \"editing\" a list of the files in a directory and
1667 \(optionally) its subdirectories, in the format of `ls -lR'.
1668 Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
1669 \"Editing\" means that you can run shell commands on files, visit,
1670 compress, load or byte-compile them, change their file attributes
1671 and insert subdirectories into the same buffer. You can \"mark\"
1672 files for later commands or \"flag\" them for deletion, either file
1673 by file or all files matching certain criteria.
1674 You can move using the usual cursor motion commands.\\<dired-mode-map>
1675 Letters no longer insert themselves. Digits are prefix arguments.
1676 Instead, type \\[dired-flag-file-deletion] to flag a file for Deletion.
1677 Type \\[dired-mark] to Mark a file or subdirectory for later commands.
1678 Most commands operate on the marked files and use the current file
1679 if no files are marked. Use a numeric prefix argument to operate on
1680 the next ARG (or previous -ARG if ARG<0) files, or just `1'
1681 to operate on the current file only. Prefix arguments override marks.
1682 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
1683 to see why something went wrong.
1684 Type \\[dired-unmark] to Unmark a file or all files of a subdirectory.
1685 Type \\[dired-unmark-backward] to back up one line and unflag.
1686 Type \\[dired-do-flagged-delete] to eXecute the deletions requested.
1687 Type \\[dired-find-file] to Find the current line's file
1688 (or dired it in another buffer, if it is a directory).
1689 Type \\[dired-find-file-other-window] to find file or dired directory in Other window.
1690 Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1691 Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1692 Type \\[dired-do-copy] to Copy files.
1693 Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches.
1694 Type \\[revert-buffer] to read all currently expanded directories aGain.
1695 This retains all marks and hides subdirs again that were hidden before.
1696 SPC and DEL can be used to move down and up by lines.
1698 If Dired ever gets confused, you can either type \\[revert-buffer] \
1700 directories again, type \\[dired-do-redisplay] \
1701 to relist a single or the marked files or a
1702 subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
1703 again for the directory tree.
