Check out my site on this page (
http://strategy.jediknight.net/jka/setup_basic.shtml#cfg). You can edit these cfg files to your liking. I find that using the cap lock to move forward and left control to move back, a & d to strafe, left click for fire1, right click for jump, and left Alt for secondary fire (I have a five button mouse, so I set my other buttons to saber style, activate saber, and switch to sniper rifle, while the mouse wheel changes weapons). This gives me more room to use the other force powers, and I only bind keys to the ones I need at the time, and bind keys to each of the cfg files so I can switch between them quickly.
For example, I set insert to lightside, home for darkside, end for combination.
