Vent right off the bat is set up with Ctrl (I believe) as your speak key. (well atleast for me). The fact that I have things key-bound to ctrl + ? (on my 90), I hit wrong things when trying to talk as I have ctrl held down. But if vent is able to be made hands free, I would see a point in it.
Also, Ill quit derailing the thread. Hope everything goes well!
