492d2437 RS |
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> | |

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] | |
