first post with this account, but I am this same john gilmore: 6 Months In ⇢ What I Wish I Knew on Day 1 With Keyboard Maestro
I am just sharing this as a fun example. It's a way to unmute and mute myself during Zoom calls without having to use a remote or touch the keyboard.
15 second video showing it in action:
unmute/re-mute zoom call on hand gesture Macro (v10.0.1)
Haha that is pretty cool man. Until somebody walks up behind you and gives you bunny ears 
I thought "how on earth does KM detect gestures - that's not a trigger". This macro is wonderful, and I love your creativity. Have you actually tried this in a video call? I suspect it hammers the CPU pretty hard by constantly checking for the image to match against?
I tried it today and it worked! besides having to flash the peace sign again and again hahah.
It doesn't work if I don't have a white background though, not enough contrast.
