8105 | directory. Otherwise, the application associated with | |

8107 | \"print\" - print DOCUMENT, which must be a file | |
8108 | \"explore\" - start the Windows Explorer on DOCUMENT | |
8109 | \"edit\" - launch an editor and open DOCUMENT for editing; which | |
8110 | editor is launched depends on the association for the | |
8111 | specified DOCUMENT | |
8112 | \"find\" - initiate search starting from DOCUMENT which must specify | |
8113 | a directory | |
8114 | nil - invoke the default OPERATION, or \"open\" if default is | |
8115 | not defined or unavailable | |
8116 | ||
8117 | DOCUMENT is typically the name of a document file or a URL, but can | |
8118 | also be a program executable to run, or a directory to open in the | |
8119 | Windows Explorer. | |
8120 | ||
