Ideal Keyboard setup?

Not sure which class you are, but setting up my Corsair's keys was hell. I had so many skills that I had to move around some of the keys I normally reserve for things like NPC chat or normal attack on my other characters. The entire left side of my keyboard is a mess of skills, even though I've completely removed Invisible Shot, Grenade, and SSK.

I have yet to make room for Hypnotize and Rapid Fire, which I don't have yet.
