I'm not sure if this would work, now...I think it might have on the standalone, but don't we have to use our steam profile page to change nicks in-game now?
Anyways...IS it possible to make a bind to change name with one keystroke? After playing on a server for a few hours, it's nice to take a short smoke break, but if you sit in spec, anybody joining thiunks they can jump into the game, and...well you've all seen this endless cycle for yourselves, so an AFK name is cool, but a bind for it would mean less time typing and more time to savour the sweet sweet nicotine.
