DeathAdder Macro(?) Keys

[The__Malteser]

Hi. Just got my Razer DA, but have no idea how to bind the thw okeys on the left (which i assume are the Macro keys, yes?).

I left them as Windiws Button 5 and 4 respectively, as they come, but how ca I bind them to specific commands in game? For example, if I want knife to me button 4 on the DA how do i do it?

Thanks.

EDIT: Nvm, done
