I have this in my ~/.emacs, which I think does what you want with much
less fuss:

 (global-set-key "\M-z" (function (lambda () (interactive) (scroll-down 1))))
 (global-set-key "\C-z" (function (lambda () (interactive) (scroll-up 1))))

Of course, I'm used to different keybindings, but the point is that
the code is much simpler and shorter.
