Mic Mute: 

The Mic Mute key is used to mute and unmute your mic during meetings in supported video conferencing apps. Pressing the key will mute at the system level and all connected audio input devices will be muted. This way you can be sure no one can hear you.

The Mic Mute functions slightly differently on the video conferencing app used and depends on how the apps themselves work:

• Zoom: Muting from the keyboard and muting and unmuting from the app will unmute everywhere.
• MS Teams: Muting from the keyboard and muting and unmuting from the app will not unmute everywhere. You should use the keyboard to unmute.
• Google Meet: Muting from the keyboard and muting and unmuting from the app will not unmute everywhere. You should use the keyboard to unmute.
