For those that don't know, its a key that toggle mutes your team for the remainder of the match, just until the last frag or bomb defused/explode. Its a great key for solo and stacks because sometimes, people mean well but they just talk to much.

It helps you get in the zone, esspecially when there is no more info the team can give you, and doesn't require mid match going in and muting unmuting everyone again and again which is unfeasible.

It really is a super minor thing that I think most people would genuinely appreciate. At least I cant help but think it would make my life easier at least once a match.
