I have a similar keyboard set up as you Cinder. Arrow keys to move, Keypad Ins for Use or Interact, RShift to Jump, RCtrl to Crouch, Enter for Reload, the 6 buttons above arrow keys and the other nearby keypad buttons for other stuff. I tried to switch to PL:" once but that just felt wrong. This is why I hate these new keyboards that lack keypads and don't have those 6 keys lined in 2 sets of 3.
