For other games (no names named) I'm able to bind my HOTAS keys as though they are modifiers, for example, when Shift is used with another key, (Shift + A, Shift is a modifier) However, in the X4 settings i am unable to do this with my HOTAS buttons, they instantly recognise as single keypresses and don't allow me to use modifying keys with them, so for example i couldnt bind shift + button 5 of my HOTAS, Likewise, i'm not able to use button 5 + any of the other buttons on the HOTAS as i would like.
And example here, in previous space titles i've been able to use button 5 and the rudder controls to control my strafe, i.e right rudder strafe right, left rudder strafe left, button 5 + right rudder to strafe down, and button 5 + left rudder to strafe up, This is what i was hoping to do with X4, however i cant currently figure out how to do it.
I know Shift, and Control are recognised as modifiers somewhere, but no idea how, if at all i can add other keys to that exlusive list

Any advice?
