8305 What operations can be used depends on the particular DOCUMENT and its
8306 handler application, but typically it is one of the following common
8307 operations:
8308
8309 \"open\" - open DOCUMENT, which could be a file, a directory, or an
8310 executable program. If it is an application, that
8311 application is launched in the current buffer's default
8312 directory. Otherwise, the application associated with
8313 DOCUMENT is launched in the buffer's default directory.
8314 \"print\" - print DOCUMENT, which must be a file
8315 \"explore\" - start the Windows Explorer on DOCUMENT
8316 \"edit\" - launch an editor and open DOCUMENT for editing; which
8317 editor is launched depends on the association for the
8318 specified DOCUMENT
8319 \"find\" - initiate search starting from DOCUMENT which must specify
8320 a directory
8321 nil - invoke the default OPERATION, or \"open\" if default is
8322 not defined or unavailable
8323
8324 DOCUMENT is typically the name of a document file or a URL, but can
8325 also be a program executable to run, or a directory to open in the
8326 Windows Explorer.
8327
8328 If DOCUMENT is a program executable, the optional third arg PARAMETERS
8329 can be a string containing command line parameters that will be passed
8330 to the program; otherwise, PARAMETERS should be nil or unspecified.
8331
8332 Optional fourth argument SHOW-FLAG can be used to control how the
8333 application will be displayed when it is invoked. If SHOW-FLAG is nil
8334 or unspecified, the application is displayed normally, otherwise it is
8335 an integer representing a ShowWindow flag:
