7516 window, otherwise it is displayed at the mouse position, with offset
7517 DY added (default is -10).

8059 This is a wrapper around the ShellExecute system function, which
8060 invokes the application registered to handle OPERATION for DOCUMENT.
8061
8062 OPERATION is either nil or a string that names a supported operation.
8063 What operations can be used depends on the particular DOCUMENT and its
8064 handler application, but typically it is one of the following common
8065 operations:
8066
8067 \"open\" - open DOCUMENT, which could be a file, a directory, or an
8068 executable program. If it is an application, that
8069 application is launched in the current buffer's default
8070 directory. Otherwise, the application associated with
8071 DOCUMENT is launched in the buffer's default directory.
8072 \"print\" - print DOCUMENT, which must be a file
8073 \"explore\" - start the Windows Explorer on DOCUMENT
8074 \"edit\" - launch an editor and open DOCUMENT for editing; which
8075 editor is launched depends on the association for the
8076 specified DOCUMENT
8077 \"find\" - initiate search starting from DOCUMENT which must specify
8078 a directory
8079 nil - invoke the default OPERATION, or \"open\" if default is
8080 not defined or unavailable
8081
8082 DOCUMENT is typically the name of a document file or a URL, but can
8083 also be a program executable to run, or a directory to open in the
8084 Windows Explorer.
8085
8086 If DOCUMENT is a program executable, the optional third arg PARAMETERS
8087 can be a string containing command line parameters that will be passed
8088 to the program; otherwise, PARAMETERS should be nil or unspecified.
8089
8090 Optional fourth argument SHOW-FLAG can be used to control how the
8091 application will be displayed when it is invoked. If SHOW-FLAG is nil
8092 or unspecified, the application is displayed normally, otherwise it is
8093 an integer representing a ShowWindow flag:
8094
8095 0 - start hidden
8096 1 - start normally
8097 3 - start maximized
