8064 This is a wrapper around the ShellExecute system function, which

8067 OPERATION is either nil or a string that names a supported operation.
8068 What operations can be used depends on the particular DOCUMENT and its
8069 handler application, but typically it is one of the following common
8070 operations:
8071
8072 \"open\" - open DOCUMENT, which could be a file, a directory, or an
8073 executable program. If it is an application, that
8074 application is launched in the current buffer's default
8075 directory. Otherwise, the application associated with
8076 DOCUMENT is launched in the buffer's default directory.
8077 \"print\" - print DOCUMENT, which must be a file
8078 \"explore\" - start the Windows Explorer on DOCUMENT
8079 \"edit\" - launch an editor and open DOCUMENT for editing; which
8080 editor is launched depends on the association for the
8081 specified DOCUMENT
8082 \"find\" - initiate search starting from DOCUMENT which must specify
8083 a directory
8084 nil - invoke the default OPERATION, or \"open\" if default is
8085 not defined or unavailable
8086
8087 DOCUMENT is typically the name of a document file or a URL, but can
8088 also be a program executable to run, or a directory to open in the
8089 Windows Explorer.
8090
8091 If DOCUMENT is a program executable, the optional arg PARAMETERS can
8092 be a string containing command line parameters that will be passed to
8093 the program; otherwise, PARAMETERS should be nil or unspecified.
8094
8095 Second optional argument SHOW-FLAG can be used to control how the
8096 application will be displayed when it is invoked. If SHOW-FLAG is nil
8097 or unspceified, the application is displayed normally, otherwise it is
8098 an integer representing a ShowWindow flag:

8101 1 - start normally
