The mouse-wheel event is special in that it contains extra info about
direction and magnitude. The current CVS uses wheel-up and wheel-down
because they are a lot easier for the end user to work with, but for
21.3, if you look in lisp/term/w32-win.el, you should be able to find
the code that deals with the [mouse-wheel] event so you can copy it
and customize it yourself.
