1020 \"Editing\" means that you can run shell commands on files, visit,
1021 compress, load or byte-compile them, change their file attributes
1022 and insert subdirectories into the same buffer. You can \"mark\"
1023 files for later commands or \"flag\" them for deletion, either file
1024 by file or all files matching certain criteria.
1025 You can move using the usual cursor motion commands.\\<dired-mode-map>
1026 Letters no longer insert themselves. Digits are prefix arguments.
1027 Instead, type \\[dired-flag-file-deletion] to flag a file for Deletion.
1028 Type \\[dired-mark] to Mark a file or subdirectory for later commands.
1029 Most commands operate on the marked files and use the current file
1030 if no files are marked. Use a numeric prefix argument to operate on
1031 the next ARG (or previous -ARG if ARG<0) files, or just `1'
1032 to operate on the current file only. Prefix arguments override marks.
1033 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
1034 to see why something went wrong.
1035 Type \\[dired-unmark] to Unmark a file or all files of a subdirectory.
1036 Type \\[dired-unmark-backward] to back up one line and unflag.
1037 Type \\[dired-do-flagged-delete] to eXecute the deletions requested.
1038 Type \\[dired-advertised-find-file] to Find the current line's file
1039 (or dired it in another buffer, if it is a directory).
1040 Type \\[dired-find-file-other-window] to find file or dired directory in Other window.
1041 Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1042 Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1043 Type \\[dired-do-copy] to Copy files.
1044 Type \\[dired-sort-toggle-or-edit] to toggle sorting by name/date or change the `ls' switches.
1045 Type \\[revert-buffer] to read all currently expanded directories again.
1046 This retains all marks and hides subdirs again that were hidden before.
1047 SPC and DEL can be used to move down and up by lines.
1049 If dired ever gets confused, you can either type \\[revert-buffer] \
1051 directories again, type \\[dired-do-redisplay] \
1052 to relist a single or the marked files or a
1053 subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
1054 again for the directory tree.
