When you're being productive, a single window may not be enough to complete your task. Most computers have keyboard shortcuts or touchpad gestures to switch between windows, but using too many windows can be confusing. Chromebooks include great multitasking features in the ChromeOS operating system. One feature is split screen mode, which puts two windows side by side to use two applications or windows simultaneously. These work well on all Chromebooks but look best on some of our favorite Chromebooks with larger screens. This guide walks you through how to use the split screen feature on your Chromebook.
