Zoom's Press-to-Unmute Feature

One of the most useful Zoom tricks I've learned is that if you are muted at a computer with a keyboard, you can press and hold the space bar to unmute yourself.  When you release the space bar, you'll be muted again. This may be useful for classes and other big group settings where most participants stay muted except for relatively brief periods to ask or answer questions. The space bar shortcut feels much quicker and more spontaneous than moving a mouse to alter a "mute/unmute" icon.

Note that some people may need to enable the feature, and I'm not aware of a similar trick for tablets or phones. But here's a link to some other Zoom features people may find helpful.
