8198 What operations can be used depends on the particular DOCUMENT and its
8199 handler application, but typically it is one of the following common
8200 operations:
8201
8202 \"open\" - open DOCUMENT, which could be a file, a directory, or an
8203 executable program. If it is an application, that
8204 application is launched in the current buffer's default
8205 directory. Otherwise, the application associated with
8206 DOCUMENT is launched in the buffer's default directory.
8207 \"print\" - print DOCUMENT, which must be a file
8208 \"explore\" - start the Windows Explorer on DOCUMENT
8209 \"edit\" - launch an editor and open DOCUMENT for editing; which
8210 editor is launched depends on the association for the
8211 specified DOCUMENT
8212 \"find\" - initiate search starting from DOCUMENT which must specify
8213 a directory
8214 nil - invoke the default OPERATION, or \"open\" if default is
8215 not defined or unavailable
8216
8217 DOCUMENT is typically the name of a document file or a URL, but can
8218 also be a program executable to run, or a directory to open in the
8219 Windows Explorer.
8220
8221 If DOCUMENT is a program executable, the optional arg PARAMETERS can
8222 be a string containing command line parameters that will be passed to
8223 the program; otherwise, PARAMETERS should be nil or unspecified.
8224
8225 Second optional argument SHOW-FLAG can be used to control how the
8226 application will be displayed when it is invoked. If SHOW-FLAG is nil
8227 or unspceified, the application is displayed normally, otherwise it is
8228 an integer representing a ShowWindow flag:
