Thanks. I’m still in the learning exploration fase, but when I get more into it I think it will become more intuitive.
I found that scrolling works by holding the MMB on the pen and dragging up down. The only problem is when you are at the bottom of the screen, because the pen can’t move further down. Then you need to flick the pen up first before scrolling down again. There is a scrollbar on the right side as well, maybe that’s easier.
