;; w32-win.el:  this file is loaded from ../lisp/startup.el when it recognizes
;; that W32 windows are to be used.  Command line switches are parsed and those
;; pertaining to W32 are processed and removed from the command line.  The
;; W32 display is opened and hooks are set for popping up the initial window.

This initially activates the first menu-bar item, and you can then navigate
with the arrow keys, select a menu entry with the Return key or cancel with
the Escape key.  If FRAME has no menu bar, this function does nothing.
