If you are writing a report in Microsoft Word, referencing numbers in a Safari browser window, and chatting with coworkers in Slack, manually dragging your mouse down to the Dock to click a different icon every ten seconds is incredibly inefficient. Every time you take your hand off the keyboard to grab the mouse, you break your workflow. Power users bypass the Dock entirely by using a built-in macOS feature called the App Switcher.
What is the App Switcher?
The App Switcher is a heads-up display (HUD) that temporarily overlays your screen, showing large, easy-to-read icons of every single application currently running on your Mac. It allows you to rapidly jump between active programs using only two fingers.
How to Activate and Use the Switcher
The App Switcher is controlled entirely by a single, powerful keyboard shortcut: Command + Tab.
- Using your thumb, press and hold down the Command (⌘) key on your keyboard. Do not let go of it.
- With your ring or middle finger, tap the Tab key once.
A translucent horizontal bar will instantly appear in the dead center of your screen, displaying the icons of your open apps. The app you were just using will be second from the left, and the app you are switching to will be highlighted.
- While continuing to hold down the Command key, tap the Tab key repeatedly to move the highlight box to the right, cycling through all your open apps.
- When the highlight box lands on the app you want (e.g., Safari), release the Command key entirely.
The horizontal bar will disappear, and Safari will instantly jump to the foreground, ready for you to use.
Advanced App Switcher Tricks
Once you master the basic Command + Tab motion, you can use the App Switcher to manage your Mac at lightning speed.
- Go Backwards: If you accidentally tap Tab too many times and pass the app you wanted, don’t cycle all the way through again. Keep holding Command, but press the Tilde (~) key (the key directly above Tab) to cycle the highlight box backward to the left.
- Quickly Quit Apps: If you see an app in the Switcher that you no longer need, you can kill it instantly. Cycle the highlight box over the app’s icon, keep holding Command, and press the Q key. The app will quit in the background without you ever needing to open it.
- Hide Apps: If you want an app to stay running but want it off your screen, highlight it in the Switcher and press the H key. The window will vanish, instantly decluttering your desktop.
