Hi,
for operating knobs in the cockpit, the mouse scroll is the ideal input method. However in FI the mouse location is bind to the direction of the head. therefore using the scrollwheel is very difficult unless you keep your head very steady.
to solve this problem I imagine 2 solutions:
option 1:
bind a key that , when pressed, will freeze the position of the mouse in the VC.
option 2:
when selecting a cockpit element such as a rotary knob, the scrollwheel get automatically bind to it.
cheers
