Why are my keyboard shortcuts not working Mac?
Make sure you're using the latest version of the app. If the keyboard shortcut uses a function key, you may also need to press and hold the Fn key or the Globe key on the keyboard to perform the shortcut (depending on your Mac model, if you're using a Magic Keyboard, and how you set an option in Keyboard settings).
