As left handed, i use to strike arrow keys instead of Q Z S D . Worthy for moving units or vehicles.
Discovering 3den, I'm stuck with the arrow keys not working.
And it's a pain to adapt Q Z S D only for 3den.
Thanks for the effort!
But:
whatever new keys don't work for 3den camera New keys binding can work for camera (from console), but as arrows (very interesting for left handed) are hardcoded for the setting menu Focus, aperture, brightness... you can't use them without changing these settings. Too bad!
Next time perhaps.
