Keybind for Swapping between PTT/Voice Activated Mode

A keybind or hotkey for swapping between PTT and voice activation mode when in voice chats would be nice. I frequently switch as I will hangout in a voice chat while playing games that require voice chat and then I will switch to a different game that doesnt have voice chat in game. Not having to enter the settings menu to make that change would be a nice quality of life improvement.
