Diablo® III

Hey my fellow Diablo3 fans.

I know its not really a Diablo 3 related topic but I think this is just the place one could know.

I just bought a D3 steelseries mouse and wonder how I could possibly put in a macro on one of the 4 customizable buttons (button 3 and 4) which toggles a key on/off.

The thought process behind this is that I want a button on my mouse to toggle on my monks ability 'long reach' to autoattack everything that walks before me. That works just fine if I hold down the number the skill is on. But, lazy as I am I don't want to press it all the time. So a toggle function would be nice :)

Glad if anyone could help me with that task :)
