I use the scroll wheel for weapons, stupid bad habit cos I ALWAYS get shot while flicking through them to see what Ive got and I'll twitch to shoot and pick up a nade

Using mouse buttons for voip is a gr8 idea too, I've done it since I started playing PR
Now you've finally decided to become a a real man instead of a silent mute try learning some quick radio protocol.
It can help loads. Far too many people I know with mics do this.. "errm Theres enemies somewhere, not sure where, theyre shooting though, could be from there... Not sure though"

"taking Fire! Pinned down... possible several hostiles northeast or north of my location"

) and then the peaceful chatter is broken by a hostile advance
