Actually it’s easier to use the mouse, scroll wheel controls zoom and hold the left mouse button down and then move the mouse to pan Left Right and Up down.
Works very well, just need your camera up above the cabin roof to get a better view.
I found when editing mine if you reduce the viewing angle to less than 45degrees (to zoom in) it starts to look a bit ordinary but between 90 & 45/50 it zooms & still looks fine.
I guess a bit more playing is in order.
