<.< I'm pretty much pressing all the buttons all the time... but I have too. The scroll wheel is the only aception I have that bound to Sprint but don't use it constantly. The 2 extra buttons M3 and M4 are triply bound. M4 = Strafe Left, M5 = Strafe Right, Ctrl+M4= Place, Ctrl+M5 = Sacred Soil, Alt+M4= Steady, Alt+ M5 = Obey. I don't think I could function as a healer without all the keybindings on my mouse or at least not optimally. It seems like the mouse is somehow trying to highlight text as if I were in a word document or something... I don't know but it's annoying.
