| 1540 | \(optionally) its subdirectories, in the format of `ls -lR'. |
| 1541 | Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise. |
| 1542 | \"Editing\" means that you can run shell commands on files, visit, |
| 1543 | compress, load or byte-compile them, change their file attributes |
| 1544 | and insert subdirectories into the same buffer. You can \"mark\" |
| 1545 | files for later commands or \"flag\" them for deletion, either file |
| 1546 | by file or all files matching certain criteria. |
| 1547 | You can move using the usual cursor motion commands.\\<dired-mode-map> |
| 1548 | Letters no longer insert themselves. Digits are prefix arguments. |
| 1549 | Instead, type \\[dired-flag-file-deletion] to flag a file for Deletion. |
| 1550 | Type \\[dired-mark] to Mark a file or subdirectory for later commands. |
| 1551 | Most commands operate on the marked files and use the current file |
| 1552 | if no files are marked. Use a numeric prefix argument to operate on |
| 1553 | the next ARG (or previous -ARG if ARG<0) files, or just `1' |
| 1554 | to operate on the current file only. Prefix arguments override marks. |
| 1555 | Mark-using commands display a list of failures afterwards. Type \\[dired-summary] |
| 1556 | to see why something went wrong. |
| 1557 | Type \\[dired-unmark] to Unmark a file or all files of a subdirectory. |
| 1558 | Type \\[dired-unmark-backward] to back up one line and unflag. |
| 1559 | Type \\[dired-do-flagged-delete] to eXecute the deletions requested. |
| 1560 | Type \\[dired-advertised-find-file] to Find the current line's file |
| 1561 | (or dired it in another buffer, if it is a directory). |
| 1562 | Type \\[dired-find-file-other-window] to find file or dired directory in Other window. |
| 1563 | Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer. |
| 1564 | Type \\[dired-do-rename] to Rename a file or move the marked files to another directory. |
| 1565 | Type \\[dired-do-copy] to Copy files. |
| 1566 | Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches. |
| 1567 | Type \\[revert-buffer] to read all currently expanded directories aGain. |
| 1568 | This retains all marks and hides subdirs again that were hidden before. |
| 1569 | SPC and DEL can be used to move down and up by lines. |
| 1570 | |
| 1571 | If Dired ever gets confused, you can either type \\[revert-buffer] \ |
| 1572 | to read the |
| 1573 | directories again, type \\[dired-do-redisplay] \ |
| 1574 | to relist a single or the marked files or a |
| 1575 | subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer |
| 1576 | again for the directory tree. |
