7067 | application is launched in the current buffer's default | |
7068 | directory. Otherwise, the application associated with | |
7069 | DOCUMENT is launched in the buffer's default directory. | |
7070 | \"print\" - print DOCUMENT, which must be a file | |
7071 | \"explore\" - start the Windows Explorer on DOCUMENT | |
7072 | \"edit\" - launch an editor and open DOCUMENT for editing; which | |
7073 | editor is launched depends on the association for the | |
7074 | specified DOCUMENT | |
7075 | \"find\" - initiate search starting from DOCUMENT which must specify | |
7076 | a directory | |
7077 | nil - invoke the default OPERATION, or \"open\" if default is | |
7078 | not defined or unavailable | |
7079 | ||
7080 | DOCUMENT is typically the name of a document file or a URL, but can | |
7081 | also be a program executable to run, or a directory to open in the | |
7082 | Windows Explorer. | |
7083 | ||

7084 | If DOCUMENT is a program executable, the optional third arg PARAMETERS |
