No way to bind middle click

That would be because the game registers M3 click as M1click so when you click your middle mouse wheel it acts like clicking the mouse, can click drag with it also, can rebind the scroll on the wheel to rotate so instead of zooming it turns buildings.

Ah, I just used my mouse software to rebind my zoom button with the letter O since I don't use that mouse button anyway.
