[ZeroX4]

when playing with gamepad, its annoying to reach out F12 in a middle of a fight

and there is program called lightscreen which lets you map any key to make screenshots also saves screenshoots as you do them
maybe you if sacrificing 1 button of ur gamepad is too much for you
map like ctrl to L3 and M to R3 and then in lightscreen make that combo do screenshot (L3 and R3 is analog key press)
