8080 This is a wrapper around the ShellExecute system function, which

8083 OPERATION is either nil or a string that names a supported operation.
8084 What operations can be used depends on the particular DOCUMENT and its
8085 handler application, but typically it is one of the following common
8086 operations:
8087
8088 \"open\" - open DOCUMENT, which could be a file, a directory, or an
8089 executable program. If it is an application, that
8090 application is launched in the current buffer's default
8091 directory. Otherwise, the application associated with
8092 DOCUMENT is launched in the buffer's default directory.
8093 \"print\" - print DOCUMENT, which must be a file
8094 \"explore\" - start the Windows Explorer on DOCUMENT
8095 \"edit\" - launch an editor and open DOCUMENT for editing; which
8096 editor is launched depends on the association for the
8097 specified DOCUMENT
8098 \"find\" - initiate search starting from DOCUMENT which must specify
8099 a directory
8100 nil - invoke the default OPERATION, or \"open\" if default is
8101 not defined or unavailable
8102
8103 DOCUMENT is typically the name of a document file or a URL, but can
8104 also be a program executable to run, or a directory to open in the
8105 Windows Explorer.
8106
8107 If DOCUMENT is a program executable, the optional arg PARAMETERS can
8108 be a string containing command line parameters that will be passed to
8109 the program; otherwise, PARAMETERS should be nil or unspecified.
8110
8111 Second optional argument SHOW-FLAG can be used to control how the
8112 application will be displayed when it is invoked. If SHOW-FLAG is nil
8113 or unspceified, the application is displayed normally, otherwise it is
8114 an integer representing a ShowWindow flag:

8117 1 - start normally
