Rebinding my Perdition Mouse.

Right, I've got a nifty new Perdition, that I really like, and it's got a natty fire button that I'd like to rebind to attack move click. Hoping someone here will know how to rebind this fire button on this, so that I can go back to having attack move as well as normal lmb functionality. Thanks in advance.

By this, I mean, what name do I put in config for the perdition mouse, or what setting do I use on the perdition program to do attack move click?

Phrae.
