Why Use Mac Function Keys?

If you've ever used a keyboard shortcut, you know how simple and fast it is. The time it takes to move your hand to your mouse or trackpad and navigate to the action you wish to take is cut short thanks to the shortcut. The function keys work the same exact way, saving you time as you work, surf the internet, or game.

Some apps allow you to customize the function keys to fit your preferences. You can also change your function keys to match your own shortcuts by remapping them. If there's an action you take often using your Mac, the functions key can help.

Do you have a MacBook Pro (15-inch, 2016 and later) or a MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports and later)? If so, your physical function keys are replaced by the Touch Bar, which changes automatically based on the apps you're using.
