Different Keys.

I looked in the FAQ's but couldnt find out if there are other keys you can use instead of the arrows.
Sorry if I missed the answer to this.

You can use either arrows, meaning the arrow keys or the numpad arrows..
I use Left Down and 8 6... helps me out a ton..

Yep... Just like Cyan said, there aren't any other keys that you can use (As of now), but you can use either the arrow keys on the actual arrow pad, or the arrow keys on the numpad, or use a mixture of both, and if you play two handed or spread, then using both like Cyan mentioned is a good idea.
