When u press some nuber then unit action list pops up where u can select move, follow, attack etc. But it seems that i cant find a button with what to select them. Can anybody help?

Thank you.

I had that problem as well, for some reason, Grin assumes we all have clickable mice. Go into your control assignments and find the control assigned to mouse 2. change it to a letter on your keyboard that isn't being used. When you are in the game, and the scroll menu comes up, scroll to where you want and hit the letter you used.
