Steering Wheel Setup

[Unco]

I feel a little embarrassed about this, but I've just activated Scania Truck Driving Simulator and I am having trouble setting up the shifter in my Logitech Driving Force GT.

In ETS2, I just click the shifter forwards or backwards to go through the gears, kind of like a tiptronic box, except that if I keep clicking back, I go all the way into Reverse.

I want to do the same in Scania Truck Driving Simulator, but I'm not sure how to do this. The gearbox settings page looks like this. I hope someone can help.

Nevermind. I figured it out. I had to go into keyboard controls, instead of 'controller'.
