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