HOW TO Customise your Magic Keyboard >
1 Choose repeat options
In System Preferences > Keyboard, choose the Keyboard tab. Use the sliders to set how long you must hold down a key until it repeats (Delay Until Repeat), and how quickly it repeats after that (Key Repeat).
2 Set function keys
By default, function keys are media keys. However, if you want to use them as function keys, check ‘Use F1, F2 etc as standard function keys’. Use the menu above to set what the Globe key does. Choose settings for the backlight.
3 Change shortcuts
macOS has a number of standard keyboard shortcuts (see left), but you can change them. Go to System Prefs > Keyboard > Shortcuts. Choose a category, then a shortcut, click on the key combination and type a new one.
