8072 This is a wrapper around the ShellExecute system function, which

8075 OPERATION is either nil or a string that names a supported operation.
8076 What operations can be used depends on the particular DOCUMENT and its
8077 handler application, but typically it is one of the following common
8078 operations:
8079
8080 \"open\" - open DOCUMENT, which could be a file, a directory, or an
8081 executable program. If it is an application, that
8082 application is launched in the current buffer's default
8083 directory. Otherwise, the application associated with
8084 DOCUMENT is launched in the buffer's default directory.
8085 \"print\" - print DOCUMENT, which must be a file
8086 \"explore\" - start the Windows Explorer on DOCUMENT
8087 \"edit\" - launch an editor and open DOCUMENT for editing; which
8088 editor is launched depends on the association for the
8089 specified DOCUMENT
8090 \"find\" - initiate search starting from DOCUMENT which must specify
8091 a directory
8092 nil - invoke the default OPERATION, or \"open\" if default is
8093 not defined or unavailable
8094
8095 DOCUMENT is typically the name of a document file or a URL, but can
8096 also be a program executable to run, or a directory to open in the
8097 Windows Explorer.
8098
8099 If DOCUMENT is a program executable, the optional arg PARAMETERS can
8100 be a string containing command line parameters that will be passed to
8101 the program; otherwise, PARAMETERS should be nil or unspecified.
8102
8103 Second optional argument SHOW-FLAG can be used to control how the
8104 application will be displayed when it is invoked. If SHOW-FLAG is nil
8105 or unspceified, the application is displayed normally, otherwise it is
8106 an integer representing a ShowWindow flag:

8109 1 - start normally
