5741 A tooltip window is a small window displaying a string.
5743 This is an internal function; Lisp code should call `tooltip-show'.
5745 FRAME nil or omitted means use the selected frame.
5747 PARMS is an optional list of frame parameters which can be
5748 used to change the tooltip's appearance.
5750 Automatically hide the tooltip after TIMEOUT seconds. TIMEOUT nil
5751 means use the default timeout of 5 seconds.
5753 If the list of frame parameters PARMS contains a `left' parameter,
5754 the tooltip is displayed at that x-position. Otherwise it is
5755 displayed at the mouse position, with offset DX added (default is 5 if
5756 DX isn't specified). Likewise for the y-position; if a `top' frame
5757 parameter is specified, it determines the y-position of the tooltip
5758 window, otherwise it is displayed at the mouse position, with offset
5759 DY added (default is -10).
5761 A tooltip's maximum size is specified by `x-max-tooltip-size'.
5762 Text larger than the specified size is clipped. */)

: /* Get Windows to perform OPERATION on DOCUMENT.
6299 This is a wrapper around the ShellExecute system function, which
6300 invokes the application registered to handle OPERATION for DOCUMENT.
6302 OPERATION is either nil or a string that names a supported operation.
6303 What operations can be used depends on the particular DOCUMENT and its
6304 handler application, but typically it is one of the following common
6307 \"open\" - open DOCUMENT, which could be a file, a directory, or an
6308 executable program. If it is an application, that
6309 application is launched in the current buffer's default
6310 directory. Otherwise, the application associated with
6311 DOCUMENT is launched in the buffer's default directory.
6312 \"print\" - print DOCUMENT, which must be a file
6313 \"explore\" - start the Windows Explorer on DOCUMENT
6314 \"edit\" - launch an editor and open DOCUMENT for editing; which
6315 editor is launched depends on the association for the
6317 \"find\" - initiate search starting from DOCUMENT which must specify
6319 nil - invoke the default OPERATION, or \"open\" if default is
6320 not defined or unavailable
6322 DOCUMENT is typically the name of a document file or a URL, but can
6323 also be a program executable to run, or a directory to open in the
6326 If DOCUMENT is a program executable, the optional third arg PARAMETERS
6327 can be a string containing command line parameters that will be passed
6328 to the program; otherwise, PARAMETERS should be nil or unspecified.
6330 Optional fourth argument SHOW-FLAG can be used to control how the
6331 application will be displayed when it is invoked. If SHOW-FLAG is nil
6332 or unspecified, the application is displayed normally, otherwise it is
6333 an integer representing a ShowWindow flag:
