Apple provides a handy ecosystem-wide feature that replaces a typed abbreviation of your choosing—say “=zoom”—with text you specify, like a link to your personal Zoom meeting room. These automatic text replacements sync via iCloud so you can use them on the Mac, iPhone, and iPad. Find them on the Mac in System Settings > Keyboard > Text Replacements and on the iPhone and iPad in Settings > General > Keyboard > Text Replacement. They’re great, but it can be mysterious when they stop working on the Mac. The likely culprit? A menu item getting turned off. So, if text replacements aren’t working in a particular app, go to the menu bar and choose Edit > Substitutions > Text Replacement to turn them back on.
