732 Mode for \"editing\" directory listings.
733 In dired, you are \"editing\" a list of the files in a directory and
734 \(optionally) its subdirectories, in the format of `ls -lR'.
735 Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
736 \"Editing\" means that you can run shell commands on files, visit,
737 compress, load or byte-compile them, change their file attributes
738 and insert subdirectories into the same buffer. You can \"mark\"
739 files for later commands or \"flag\" them for deletion, either file
740 by file or all files matching certain criteria.
741 You can move using the usual cursor motion commands.\\<dired-mode-map>
742 Letters no longer insert themselves. Digits are prefix arguments.
743 Instead, type \\[dired-flag-file-deletion] to flag a file for Deletion.
744 Type \\[dired-mark] to Mark a file or subdirectory for later commands.
745 Most commands operate on the marked files and use the current file
746 if no files are marked. Use a numeric prefix argument to operate on
747 the next ARG (or previous -ARG if ARG<0) files, or just `1'
748 to operate on the current file only. Prefix arguments override marks.
749 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
750 to see why something went wrong.
751 Type \\[dired-unmark] to Unmark a file or all files of a subdirectory.
752 Type \\[dired-unmark-backward] to back up one line and unflag.
753 Type \\[dired-do-flagged-delete] to eXecute the deletions requested.
754 Type \\[dired-advertised-find-file] to Find the current line's file
755 (or dired it in another buffer, if it is a directory).
756 Type \\[dired-find-file-other-window] to find file or dired directory in Other window.
757 Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
758 Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
759 Type \\[dired-do-copy] to Copy files.
760 Type \\[dired-sort-toggle-or-edit] to toggle sorting by name/date or change the `ls' switches.
761 Type \\[revert-buffer] to read all currently expanded directories again.
762 This retains all marks and hides subdirs again that were hidden before.
763 SPC and DEL can be used to move down and up by lines.
765 If dired ever gets confused, you can either type \\[revert-buffer] \
767 directories again, type \\[dired-do-redisplay] \
768 to relist a single or the marked files or a
769 subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
770 again for the directory tree.
