Razer Nostromo : Possible shortcut tool for painting?

[Mig]

I've been using the Belkin N52 with photoshop (as well as gaming) for several years. I work with my Left hand on the Nostromo, stylus in the right, I very rarely have to touch the actual keyboard. In my opinion it is a definite productivity booster.

-Lumens! There is a bind macro option, although it appears a bit more laborious than with my older model.

Also if you search for photoshop profiles for the Nostromo, you might find someone has already created the bindings you need.
