Optimization for non-touchscreen devices

Hello forums. I recently received a Chromebook without touchscreen capabilities. This computer does however, have support for the game. I was wondering if there was any way to bind certain keys to certain actions (example, A to dash back, L to dash forward, S to block, K to attack, a bit of a weird layout I know). Maybe this could be done in the next update or so, assuming there is a way to do this.
