Mute, start video, share your screen and raise your hand without hunting for buttons — Zoom shortcuts for Mac and Windows.
The single most useful Zoom shortcut is toggle mute — ⌘⇧A on Mac, Alt+A on Windows — and its companion push to talk: hold the Space bar to talk while muted, release to mute again. Together they solve the most common meeting problem, which is forgetting which state your mic is in. Make these automatic and you'll never be the person talking on mute.
For presenting, start/stop screen share (⌘⇧S / Alt+S) and raise hand (⌥Y / Alt+Y) are the ones to know, along with toggling the participants and chat panels to keep an eye on the room. If you run a lot of calls, enabling Zoom's global shortcuts means mute and video work even when you've clicked away to another window — handy when you're sharing slides. Compare with the Microsoft Teams shortcuts if you switch between the two.
