Your Desktop can be a busy places, with a bunch of open windows cluttering the screen. If you want to look at the Desktop or see another window, you may find yourself clicking around or using keyboard shortcuts to switch views. Did you know that you can access many of the Mac’s special views with a simple movement?
A little-known feature in macOS called Hot Corners makes this possible. The key to unlocking Hot Corners is in System Preferences (click the top left corner ) in either the Desktop & Screen Saver pane or the Mission Control pane. In either one, click the Hot Corners button (bottom left or right) to set up your hot corners.
Hot Corners can be quite useful, and how you choose to take advantage of them is completely up to you. We do recommend trying them out, you can always turn them back off if you find yourself disliking the behavior.
