Creating a Replacement: Click the + button to add a new replacement. Shortcut: Choose the shortcut you want to use (e.g., “sig” for your email signature). Be mindful of existing shortcuts you might be using. Text: Type the long phrase you want to replace. For example, “My email is john.doe@example.com”. Done: Click “Done”. Using Your Replacement: Just type your shortcut (e.g., “sig”) in a text field (email, document, code editor, etc.). macOS will automatically replace it with the full phrase.
