8239 OPERATION is either nil or a string that names a supported operation.
8240 What operations can be used depends on the particular DOCUMENT and its
8241 handler application, but typically it is one of the following common
8242 operations:
8243
8244 \"open\" - open DOCUMENT, which could be a file, a directory, or an
8245 executable program. If it is an application, that
8246 application is launched in the current buffer's default
8247 directory. Otherwise, the application associated with
8248 DOCUMENT is launched in the buffer's default directory.
8249 \"print\" - print DOCUMENT, which must be a file
8250 \"explore\" - start the Windows Explorer on DOCUMENT
8251 \"edit\" - launch an editor and open DOCUMENT for editing; which
8252 editor is launched depends on the association for the
8253 specified DOCUMENT
8254 \"find\" - initiate search starting from DOCUMENT which must specify
8255 a directory
8256 nil - invoke the default OPERATION, or \"open\" if default is
8257 not defined or unavailable
8258
8259 DOCUMENT is typically the name of a document file or a URL, but can
8260 also be a program executable to run, or a directory to open in the
8261 Windows Explorer.
8262
8263 If DOCUMENT is a program executable, the optional arg PARAMETERS can
8264 be a string containing command line parameters that will be passed to
8265 the program; otherwise, PARAMETERS should be nil or unspecified.
8266
8267 Second optional argument SHOW-FLAG can be used to control how the
8268 application will be displayed when it is invoked. If SHOW-FLAG is nil
8269 or unspceified, the application is displayed normally, otherwise it is
8270 an integer representing a ShowWindow flag:
