Like my peers, I too have trouble with changing keys. It is impossible for me to change the keybinds. It tells "This key already in use, previous setting will be disabled" whenever I change keys.

I ignored this, but found in game that only two keys, rotate guns counterclockwise and rotate guns to port, worked, and they weren't even the keybinds I wanted. I couldnt do anything else. I am using manual.

On a side note, a button to clear all keybinds for a control set should be added. That would make verification that your keys won't conflict easier than hunting to make sure that only one action per key. I also support an offline test area to trial ship setups/key setups. 

Thanks, I know the devs are working their butts off to make this work well on release.
