It is hardcoded to certain values in the FlightCtrlState class, which can be accessed by overriding the OnCtrlUpd(FlightCtrlState) function. It also seems you can modify certain input controls (yaw, pitch, roll) I haven\'t tested if it accepts changes to it. Also seems you can access it through 'FlightInputHandler.state'. The only way you can do it is like Crazygerbil suggested. It might be possible to have the hotkey editable through the .cfg file but I haven\'t tested this either.
