caps lock mutes microphone
If you’re like me, you have a ton of conference calls, and if you aren’t a complete noob, you have yourself on mute when you don’t need to talk. The problem is hunting for the mute button and no visibility when you are “on air”
For this I use Push to Talk in conjunction with Karabiner to remap caps lock to Push to Talk’s shortcut sequence (mine’s control+p). The best part is I get a blue light that goes on and off to show when i’m “on air”.
