8092 This is a wrapper around the ShellExecute system function, which

8095 OPERATION is either nil or a string that names a supported operation.
8096 What operations can be used depends on the particular DOCUMENT and its
8097 handler application, but typically it is one of the following common
8098 operations:
8099
8100 \"open\" - open DOCUMENT, which could be a file, a directory, or an
8101 executable program. If it is an application, that
8102 application is launched in the current buffer's default
8103 directory. Otherwise, the application associated with
8104 DOCUMENT is launched in the buffer's default directory.
8105 \"print\" - print DOCUMENT, which must be a file
8106 \"explore\" - start the Windows Explorer on DOCUMENT
8107 \"edit\" - launch an editor and open DOCUMENT for editing; which
8108 editor is launched depends on the association for the
8109 specified DOCUMENT
8110 \"find\" - initiate search starting from DOCUMENT which must specify
8111 a directory
8112 nil - invoke the default OPERATION, or \"open\" if default is
8113 not defined or unavailable
8114
8115 DOCUMENT is typically the name of a document file or a URL, but can
8116 also be a program executable to run, or a directory to open in the
8117 Windows Explorer.
8118
8119 If DOCUMENT is a program executable, the optional arg PARAMETERS can
8120 be a string containing command line parameters that will be passed to
8121 the program; otherwise, PARAMETERS should be nil or unspecified.
8122
8123 Second optional argument SHOW-FLAG can be used to control how the
8124 application will be displayed when it is invoked. If SHOW-FLAG is nil
8125 or unspceified, the application is displayed normally, otherwise it is
8126 an integer representing a ShowWindow flag:
