Hot Corners in macOS

When you are looking to navigate between windows and applications on your Mac, Mission Control can be a wonderful utility. One feature within Mission Control, Hot Corners, helps elevate Mission Control to a higher level, greasing it's wheels and allowing your screen to fly through apps with the flick of a wrist.

Hot Corners allow you to invoke one of several pre-defined configurations when you move your mouse cursor to one of the four corners of the display. These are:

  • Mission Control
  • Application Windows
  • Desktop
  • Dashboard
  • Notification Centre
  • Launchpad
  • Start Screen Saver
  • Disable Screen Saver
  • Put Display To Sleep

For me, the most used function is Desktop. Rightly or wrongly, I tend to place documents that I'm using in the current session of work on the desktop. By configuring a Hot Corner to show me the desktop, I can grab the file I need swiftly and either embed within the current application or open as needed. This is quicker than doing so with a keyboard shortcut because my hand doesn't need to leave the trackpad.

I also have the top right corner set up to open the Notification Centre. Yes, I know that the icon for Notification Centre is in the status bar. Also, I know that I can swipe in with two fingers from the right of the screen to access it - but the former requires a touch more thinking about in order to click on the icon (not a lot I know, but enough) and the latter quite often doesn't work on the first attempt and requires multiple efforts to open. A mindless sweep of the wrist to the top right hand corner of the screen cannot fail - nor does it. It's hard to miss that.

Configuring Hot Corners is a simple affair.

Step 1 - open System Preferences

Step 2 - select Mission Control

Step 3 - click the Hot Corners button in the bottom left hand corner.

Step 4 - configure your corners by using the drop down boxes. If you do not wish to assign an action to a corner, select the - option instead.

Give it a go. If you don't like it - well, you can turn it off! It's worth a crack though.
