So I've been getting into Dota 2 recently and the game requires a lot of coordination between keyboard and mouse actions. The problem is that I've always moved the camera around using the arrow keys, which restricts my use of items (1-6) and skills/player actions (q,w,e,r,a,s). I've tried to use just the mouse to move the camera, but I always return to the four directional keys. What would you guys suggest to help me break the habit? My current idea is to just unbind the four keys so that I have to use my mouse to move the camera no matter what.
