Quit Apps With the App Switcher

So you probably know that you can use Command+Tab to switch apps. Continue to hold the Command key down and press Tab multiple times to move through the apps in the App Switcher. You can also quit an app from here by pressing Q. For instance, if you use Command+Tab and see Safari, Mail, iMovie, Preview and Calculator, the selection should start with the second one, Mail. Continue to hold Command and press Tab again to go to iMovie. Still with Command held down, press Q and iMovie will quit. You can continue to hold Command and use Tab and Q to move through the apps and quit some of them. Shift+Tab moves backwards.
