8119 This is a wrapper around the ShellExecute system function, which

8122 OPERATION is either nil or a string that names a supported operation.
8123 What operations can be used depends on the particular DOCUMENT and its
8124 handler application, but typically it is one of the following common
8125 operations:
8126
8127 \"open\" - open DOCUMENT, which could be a file, a directory, or an
8128 executable program. If it is an application, that
8129 application is launched in the current buffer's default
8130 directory. Otherwise, the application associated with
8131 DOCUMENT is launched in the buffer's default directory.
8132 \"print\" - print DOCUMENT, which must be a file
8133 \"explore\" - start the Windows Explorer on DOCUMENT
8134 \"edit\" - launch an editor and open DOCUMENT for editing; which
8135 editor is launched depends on the association for the
8136 specified DOCUMENT
8137 \"find\" - initiate search starting from DOCUMENT which must specify
8138 a directory
8139 nil - invoke the default OPERATION, or \"open\" if default is
8140 not defined or unavailable
8141
8142 DOCUMENT is typically the name of a document file or a URL, but can
8143 also be a program executable to run, or a directory to open in the
8144 Windows Explorer.
8145
8146 If DOCUMENT is a program executable, the optional arg PARAMETERS can
8147 be a string containing command line parameters that will be passed to
8148 the program; otherwise, PARAMETERS should be nil or unspecified.
8149
8150 Second optional argument SHOW-FLAG can be used to control how the
8151 application will be displayed when it is invoked. If SHOW-FLAG is nil
8152 or unspceified, the application is displayed normally, otherwise it is
8153 an integer representing a ShowWindow flag:
