As you know, you can mute and un-mute by clicking on the microphone icon.
But there is a much smarter way—simply push and hold the space bar as you talk. Then release when you have finished.
 
We should try to get used to being muted all the time and just un-mute when we wish to speak, or invited to speak by the host.
By default, your settings will allow this. If it’s not working go into your audio settings and make sure it’s checked.
