Every Monday we show you how to do something quick and cool using built-in OS X utilities such as Terminal, Apple’s command line application. These easy hacks can make life better and simpler, and don’t require any knowledge of coding — all you need is a keyboard to type 'em out!

As with other areas of OS X, animations in Mission Control are prevalent, but they do take time, and when switching your apps you want the fastest possible experience.
