in case my troubles are not really understandable or solve-able on internetz... I will ask this here so as not to create a new post and the question is related.

My mod keys (alt, ctrl, and shift) are right now used by actually pressing those keys. Is there a way i can bind them to some extra buttons on a mouse? The placement of those buttons on the keyboard is a pain for fast and comfortable mods. If i could have them on my mouse it would solve everything. I want to use my shift so much cause it is the easiest and most comfortable key to press while getting at another key.
