8055 | application is launched in the current buffer's default | |
8056 | directory. Otherwise, the application associated with | |
8057 | DOCUMENT is launched in the buffer's default directory. | |
8058 | \"print\" - print DOCUMENT, which must be a file | |
8059 | \"explore\" - start the Windows Explorer on DOCUMENT | |
8060 | \"edit\" - launch an editor and open DOCUMENT for editing; which | |
8061 | editor is launched depends on the association for the | |
8062 | specified DOCUMENT | |
8063 | \"find\" - initiate search starting from DOCUMENT which must specify | |
8064 | a directory | |
8065 | nil - invoke the default OPERATION, or \"open\" if default is | |
8066 | not defined or unavailable | |
8067 | ||
8068 | DOCUMENT is typically the name of a document file or a URL, but can | |
8069 | also be a program executable to run, or a directory to open in the | |
8070 | Windows Explorer. | |
8071 | ||
8072 | If DOCUMENT is a program executable, the optional arg PARAMETERS can | |
8073 | be a string containing command line parameters that will be passed to | |
8074 | the program; otherwise, PARAMETERS should be nil or unspecified. | |
8075 | ||
8076 | Second optional argument SHOW-FLAG can be used to control how the | |
8077 | application will be displayed when it is invoked. If SHOW-FLAG is nil | |
