But what's the shortcut for the random conference tool the organizers of this meeting decided to use?

Just make it visible. It's supposed to be a tool, function over form.

Which also happens to be the shortcut for bookmarking webpages in most browsers... and Meet doesn't let you rebind this to something sane like spacebar.

Not to mention the window might not have focus when you need to use it, making it preatty unreliable.

My laptop has a mute button with a status led - an absolute godsend this year.

Yes, but they're also all different, so you need to play mind games to remember what the shortcut is for which solution.

Global hotkey would be nicer, I think.
