8354 | directory. Otherwise, the application associated with | |

8356 | \"print\" - print DOCUMENT, which must be a file | |
8357 | \"explore\" - start the Windows Explorer on DOCUMENT | |
8358 | \"edit\" - launch an editor and open DOCUMENT for editing; which | |
8359 | editor is launched depends on the association for the | |
8360 | specified DOCUMENT | |
8361 | \"find\" - initiate search starting from DOCUMENT which must specify | |
8362 | a directory | |
8363 | nil - invoke the default OPERATION, or \"open\" if default is | |
8364 | not defined or unavailable | |
8365 | ||
8366 | DOCUMENT is typically the name of a document file or a URL, but can | |
8367 | also be a program executable to run, or a directory to open in the | |
8368 | Windows Explorer. | |
