5743 A tooltip window is a small window displaying a string.
5745 This is an internal function; Lisp code should call `tooltip-show'.
5747 FRAME nil or omitted means use the selected frame.
5749 PARMS is an optional list of frame parameters which can be
5750 used to change the tooltip's appearance.
5752 Automatically hide the tooltip after TIMEOUT seconds. TIMEOUT nil
5753 means use the default timeout of 5 seconds.
5755 If the list of frame parameters PARMS contains a `left' parameter,
5756 the tooltip is displayed at that x-position. Otherwise it is
5757 displayed at the mouse position, with offset DX added (default is 5 if
5758 DX isn't specified). Likewise for the y-position; if a `top' frame
5759 parameter is specified, it determines the y-position of the tooltip
5760 window, otherwise it is displayed at the mouse position, with offset
5761 DY added (default is -10).
5763 A tooltip's maximum size is specified by `x-max-tooltip-size'.
5764 Text larger than the specified size is clipped. */)

: /* Get Windows to perform OPERATION on DOCUMENT.
6301 This is a wrapper around the ShellExecute system function, which
6302 invokes the application registered to handle OPERATION for DOCUMENT.
6304 OPERATION is either nil or a string that names a supported operation.
6305 What operations can be used depends on the particular DOCUMENT and its
6306 handler application, but typically it is one of the following common
6309 \"open\" - open DOCUMENT, which could be a file, a directory, or an
6310 executable program. If it is an application, that
6311 application is launched in the current buffer's default
6312 directory. Otherwise, the application associated with
6313 DOCUMENT is launched in the buffer's default directory.
6314 \"print\" - print DOCUMENT, which must be a file
6315 \"explore\" - start the Windows Explorer on DOCUMENT
6316 \"edit\" - launch an editor and open DOCUMENT for editing; which
6317 editor is launched depends on the association for the
6319 \"find\" - initiate search starting from DOCUMENT which must specify
6321 nil - invoke the default OPERATION, or \"open\" if default is
6322 not defined or unavailable
6324 DOCUMENT is typically the name of a document file or a URL, but can
6325 also be a program executable to run, or a directory to open in the
6328 If DOCUMENT is a program executable, the optional third arg PARAMETERS
6329 can be a string containing command line parameters that will be passed
6330 to the program; otherwise, PARAMETERS should be nil or unspecified.
6332 Optional fourth argument SHOW-FLAG can be used to control how the
6333 application will be displayed when it is invoked. If SHOW-FLAG is nil
6334 or unspecified, the application is displayed normally, otherwise it is
6335 an integer representing a ShowWindow flag:
