1182 Mode for \"editing\" directory listings.
1183 In Dired, you are \"editing\" a list of the files in a directory and
1184 \(optionally) its subdirectories, in the format of `ls -lR'.
1185 Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
1186 \"Editing\" means that you can run shell commands on files, visit,
1187 compress, load or byte-compile them, change their file attributes
1188 and insert subdirectories into the same buffer. You can \"mark\"
1189 files for later commands or \"flag\" them for deletion, either file
1190 by file or all files matching certain criteria.
1191 You can move using the usual cursor motion commands.\\<dired-mode-map>
1192 Letters no longer insert themselves. Digits are prefix arguments.
1193 Instead, type \\[dired-flag-file-deletion] to flag a file for Deletion.
1194 Type \\[dired-mark] to Mark a file or subdirectory for later commands.
1195 Most commands operate on the marked files and use the current file
1196 if no files are marked. Use a numeric prefix argument to operate on
1197 the next ARG (or previous -ARG if ARG<0) files, or just `1'
1198 to operate on the current file only. Prefix arguments override marks.
1199 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
1200 to see why something went wrong.
1201 Type \\[dired-unmark] to Unmark a file or all files of a subdirectory.
1202 Type \\[dired-unmark-backward] to back up one line and unflag.
1203 Type \\[dired-do-flagged-delete] to eXecute the deletions requested.
1204 Type \\[dired-advertised-find-file] to Find the current line's file
1205 (or dired it in another buffer, if it is a directory).
1206 Type \\[dired-find-file-other-window] to find file or dired directory in Other window.
1207 Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1208 Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1209 Type \\[dired-do-copy] to Copy files.
1210 Type \\[dired-sort-toggle-or-edit] to toggle sorting by name/date or change the `ls' switches.
1211 Type \\[revert-buffer] to read all currently expanded directories again.
1212 This retains all marks and hides subdirs again that were hidden before.
1213 SPC and DEL can be used to move down and up by lines.
1215 If dired ever gets confused, you can either type \\[revert-buffer] \
1216 to read the
1217 directories again, type \\[dired-do-redisplay] \
1218 to relist a single or the marked files or a
1219 subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
1220 again for the directory tree.
