6297 | application is launched in the current buffer's default | |
6298 | directory. Otherwise, the application associated with | |
6299 | DOCUMENT is launched in the buffer's default directory. | |
6300 | \"print\" - print DOCUMENT, which must be a file | |
6301 | \"explore\" - start the Windows Explorer on DOCUMENT | |
6302 | \"edit\" - launch an editor and open DOCUMENT for editing; which | |
6303 | editor is launched depends on the association for the | |
6304 | specified DOCUMENT | |
6305 | \"find\" - initiate search starting from DOCUMENT which must specify | |
6306 | a directory | |
6307 | nil - invoke the default OPERATION, or \"open\" if default is | |
6308 | not defined or unavailable | |
6309 | ||
6310 | DOCUMENT is typically the name of a document file or a URL, but can | |
6311 | also be a program executable to run, or a directory to open in the | |
6312 | Windows Explorer. | |
6313 | ||
02b39a28 JB |
6314 | If DOCUMENT is a program executable, the optional third arg PARAMETERS |
6315 | can be a string containing command line parameters that will be passed | |
6316 | to the program; otherwise, PARAMETERS should be nil or unspecified. | |

02b39a28 | 6318 | Optional fourth argument SHOW-FLAG can be used to control how the |
1dccd454 | 6319 | application will be displayed when it is invoked. If SHOW-FLAG is nil |
