Keyboard shortcuts are a productivity win, but they can cause confusion if something unexpected happens when you inadvertently press some system-wide key combination. For instance, you might be taken aback if you accidentally press Control-Option-Command-8 and all the colors on your Mac screen suddenly invert. Although Apple has pages listing shortcuts and the KeyCue utility can list them all for any app, a good way to see—and manage—what’s active on any Mac is to open System Settings > Keyboard > Keyboard Shortcuts (look in the same place in System Preferences in macOS 12 Monterey and earlier) and scan the categories. Disable shortcuts you’ll never use by deselecting their checkboxes, and redefine others so you’ll remember them.
