1023 | Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise. | |
1024 | \"Editing\" means that you can run shell commands on files, visit, | |
1025 | compress, load or byte-compile them, change their file attributes | |
1026 | and insert subdirectories into the same buffer. You can \"mark\" | |
1027 | files for later commands or \"flag\" them for deletion, either file | |
1028 | by file or all files matching certain criteria. | |
1029 | You can move using the usual cursor motion commands.\\<dired-mode-map> | |
1030 | Letters no longer insert themselves. Digits are prefix arguments. | |
1031 | Instead, type \\[dired-flag-file-deletion] to flag a file for Deletion. | |
1032 | Type \\[dired-mark] to Mark a file or subdirectory for later commands. | |
1033 | Most commands operate on the marked files and use the current file | |
1034 | if no files are marked. Use a numeric prefix argument to operate on | |
1035 | the next ARG (or previous -ARG if ARG<0) files, or just `1' | |
1036 | to operate on the current file only. Prefix arguments override marks. | |
1037 | Mark-using commands display a list of failures afterwards. Type \\[dired-summary] | |
1038 | to see why something went wrong. | |
1039 | Type \\[dired-unmark] to Unmark a file or all files of a subdirectory. | |
1040 | Type \\[dired-unmark-backward] to back up one line and unflag. | |
1041 | Type \\[dired-do-flagged-delete] to eXecute the deletions requested. | |
1042 | Type \\[dired-advertised-find-file] to Find the current line's file | |
1043 | (or dired it in another buffer, if it is a directory). | |
1044 | Type \\[dired-find-file-other-window] to find file or dired directory in Other window. | |
1045 | Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer. | |
1046 | Type \\[dired-do-rename] to Rename a file or move the marked files to another directory. | |
1047 | Type \\[dired-do-copy] to Copy files. | |
1048 | Type \\[dired-sort-toggle-or-edit] to toggle sorting by name/date or change the `ls' switches. | |
1049 | Type \\[revert-buffer] to read all currently expanded directories again. | |
1050 | This retains all marks and hides subdirs again that were hidden before. | |
1051 | SPC and DEL can be used to move down and up by lines. | |
1052 | ||
