How do I assign a Razer DeathAdder Black Edition key to Mission Control? I have purchased a Razer DeathAdder Black Edition mouse, and the latest Mac driver I can find for it is 1.00.  The possible assignments for the side buttons don't seem to have Mission Control buttons available for them (they only have various Expose keys available)

Is there a hack around this?  Or do I just have to do without?  Or exchange for a different Razer mouse with a more developed Mac driver?  Or just use the Mac driver for a different Razer mouse?
I've got my Razer Naga configured to work with Mission Control.

I've used the Razer drivers to set up the button I want to use to trigger Mission Control to trigger Mouse Button 3 (you can bind any button to this):


Then, I've set up System Preferences to use Mouse Button 3 to trigger Mission Control:


That's been working fine for me; no extra software required.
