Hi Community, I just signed up here because I have an (for me) important question: How do I change my key bindings for BD Armory? I am using a Thrustmaster Hotas X Joystick and I want the trigger to trigger when I press a button on my Flight Stick. I didn't find any BDA Settings in the ganme except for Gamemode etc and want to know if it's possible. Thank you!
