8104 | handler application, but typically it is one of the following common | |
8105 | operations: | |
8106 | ||
8107 | \"open\" - open DOCUMENT, which could be a file, a directory, or an | |
8108 | executable program. If it is an application, that | |
8109 | application is launched in the current buffer's default | |
8110 | directory. Otherwise, the application associated with | |
8111 | DOCUMENT is launched in the buffer's default directory. | |
8112 | \"print\" - print DOCUMENT, which must be a file | |
8113 | \"explore\" - start the Windows Explorer on DOCUMENT | |
8114 | \"edit\" - launch an editor and open DOCUMENT for editing; which | |
8115 | editor is launched depends on the association for the | |
8116 | specified DOCUMENT | |
8117 | \"find\" - initiate search starting from DOCUMENT which must specify | |
8118 | a directory | |
8119 | nil - invoke the default OPERATION, or \"open\" if default is | |
8120 | not defined or unavailable | |
8121 | ||
8122 | DOCUMENT is typically the name of a document file or a URL, but can | |
8123 | also be a program executable to run, or a directory to open in the | |
8124 | Windows Explorer. | |
8125 | ||
8126 | If DOCUMENT is a program executable, the optional arg PARAMETERS can | |
8127 | be a string containing command line parameters that will be passed to | |
8128 | the program; otherwise, PARAMETERS should be nil or unspecified. | |
8129 | ||
8130 | Second optional argument SHOW-FLAG can be used to control how the | |
8131 | application will be displayed when it is invoked. If SHOW-FLAG is nil | |
8132 | or unspceified, the application is displayed normally, otherwise it is | |
8133 | an integer representing a ShowWindow flag: | |
