How to use pen gestures for easy navigation!
You might have noticed that you cannot scroll with the pen on the Surface, here is how you can change that.
1) Go to Control Panel
2) Search for Pen and Touch
3) Under the ‘Flicks’ tab, select ‘Practice using flicks’
I recommend changing the sensitivity to Relaxed so it can better recognize a flick. Or change it to what’s more comfortable to you.
Note: Flicks don’t seem to work in Internet Explorer, but they do in Chrome.

You don’t actually explain here what a flick is.
