Bound directional keys in SOR4 to wasd; now wasd are mapped to arrow keys and vice versa, even for GRUB2, the linux bootloader. It is a HUGE pain to put in passwords now. How to fix?

Near as I remember, I was in story mode, last boss fight, easy, using Axel, first run through, when wasd stopped working. Tried "restore defaults" but it did not help. I think this was when Mr. Y mounts the mech, and controls freeze up. I didn't realize that I would not be able to move. May I suggest only disabling attack inputs for that part of the game?

I had to use arrow keys for every instance of wasd in this post. I used wasd to move my cursor (composed post in notepad).
