8318 What operations can be used depends on the particular DOCUMENT and its
8319 handler application, but typically it is one of the following common
8320 operations:
8321
8322 \"open\" - open DOCUMENT, which could be a file, a directory, or an
8323 executable program. If it is an application, that
8324 application is launched in the current buffer's default
8325 directory. Otherwise, the application associated with
8326 DOCUMENT is launched in the buffer's default directory.
8327 \"print\" - print DOCUMENT, which must be a file
8328 \"explore\" - start the Windows Explorer on DOCUMENT
8329 \"edit\" - launch an editor and open DOCUMENT for editing; which
8330 editor is launched depends on the association for the
8331 specified DOCUMENT
8332 \"find\" - initiate search starting from DOCUMENT which must specify
8333 a directory
8334 nil - invoke the default OPERATION, or \"open\" if default is
8335 not defined or unavailable
8336
8337 DOCUMENT is typically the name of a document file or a URL, but can
8338 also be a program executable to run, or a directory to open in the
8339 Windows Explorer.
8340
8341 If DOCUMENT is a program executable, the optional third arg PARAMETERS
8342 can be a string containing command line parameters that will be passed
8343 to the program; otherwise, PARAMETERS should be nil or unspecified.
8344
8345 Optional fourth argument SHOW-FLAG can be used to control how the
8346 application will be displayed when it is invoked. If SHOW-FLAG is nil
8347 or unspecified, the application is displayed normally, otherwise it is
8348 an integer representing a ShowWindow flag:
