key binding with windows and menu keys

[Tyler]

Hi,

I'd like to bind the windows key to scroll-other-window-down, as is set 
to C-M-s-v by default. I've been googling for answers, but can't figure 
out what to call the windows key. My keyboard has a full complement of 
CTRL, Shift, Esc, and Alt keys which behave as expected. It would be 
nice to make use of the 'Windows' and 'Menu' keys as well. Can anyone 
tell me how to do so?

Thanks,

Tyler

ps. the goal would be to add something like the following to my .emacs 
file, only with proper syntax:

(global-set-key "\WINDOWS-z" 'scroll-other-window-down)
