I notice that when you try to change the default controls, you can only chose keyboard controls. What I want to do is at least bind cast to mouse3, and possibly have the scroll wheel scroll through my quick slots. I was looking at the config file, and see that the default controls are indicated in hex, so I thought I would edit that, but I don't think mouse input has a hex code. Has anyone managed to do anything like this? If so, how did you do it? Thanks.

I know it's possible to assign mouse keys to do things like cast spells. Try clicking on the "Keyboard" when you go to change the buttons. I'm sure that switches it to mouse.

lol...of course it's that easy. I never even noticed that. Here I was trying to figure out hex. Thanks.
