1897 Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
1898 \"Editing\" means that you can run shell commands on files, visit,
1899 compress, load or byte-compile them, change their file attributes
1900 and insert subdirectories into the same buffer. You can \"mark\"
1901 files for later commands or \"flag\" them for deletion, either file
1902 by file or all files matching certain criteria.
1903 You can move using the usual cursor motion commands.\\<dired-mode-map>
1904 The buffer is read-only. Digits are prefix arguments.
1905 Type \\[dired-flag-file-deletion] to flag a file `D' for deletion.
1906 Type \\[dired-mark] to Mark a file or subdirectory for later commands.
1907 Most commands operate on the marked files and use the current file
1908 if no files are marked. Use a numeric prefix argument to operate on
1909 the next ARG (or previous -ARG if ARG<0) files, or just `1'
1910 to operate on the current file only. Prefix arguments override marks.
1911 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
1912 to see why something went wrong.
1913 Type \\[dired-unmark] to Unmark a file or all files of an inserted subdirectory.
1914 Type \\[dired-unmark-backward] to back up one line and unmark or unflag.
1915 Type \\[dired-do-flagged-delete] to delete (eXecute) the files flagged `D'.
1916 Type \\[dired-find-file] to Find the current line's file
1917 (or dired it in another buffer, if it is a directory).
1918 Type \\[dired-find-file-other-window] to find file or Dired directory in Other window.
1919 Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1920 Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1921 Type \\[dired-do-copy] to Copy files.
1922 Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches.
1923 Type \\[revert-buffer] to read all currently expanded directories aGain.
1924 This retains all marks and hides subdirs again that were hidden before.
1925 Use `SPC' and `DEL' to move down and up by lines.
1927 If Dired ever gets confused, you can either type \\[revert-buffer] \
1928 to read the
1929 directories again, type \\[dired-do-redisplay] \
1930 to relist the file at point or the marked files or a
1931 subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
1932 again for the directory tree.
1934 Customization variables (rename this buffer and type \\[describe-variable] on each line

4025 `*' and `?' when not surrounded by whitespace have no special

4029 If you want to use `*' as a shell wildcard with whitespace around
