I recently got a new set-up and one issue is that my mic isn't compatible with my tower. I decided to go ahead and purchase DayZ for the sheer fun of it, mic's aren't much of a necessity, I can still go round doing my stuff. Then I realised that since I have a razer blackwidow chroma with 5 macro keys on the left, is there a way I can macro them so M1 types "Friendly!" in chat and so on? Could anyone help out?
