Zac Hall, 9to5Mac:

There are a lot of little tweaks in macOS that I rely on to make a Mac feel like my own. Placing frequently accessed folders on the right side of the Dock, turning off auto-correct, and turning up mouse and trackpad tracking speed are all in this category for me.

A rather hidden but critical example is Hot Corners. My Mac just feels broken with Hot Corners disabled, and my workflow is severely slowed. Here’s how it works.

First thing first, I couldn’t agree more. Hot Corners, part of Mission Control, is an incredibly valuable part of the Mac interface. I expect most of the folks reading this are aware of this longstanding Mac feature. But if you have never taken the time to set this up, or if you are critical support for other, less knowledgable or just plain newer Mac folks, jump on over to Zac’s article and pass the knowledge along.

One thing that really appeals to me about Hot Corners is a bit of science, wrapped up under the title Fitts’ Law. From the Fitts’ Law Wikipedia page:

This scientific law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target. Fitts’s law is used to model the act of pointing, either by physically touching an object with a hand or finger, or virtually, by pointing to an object on a computer monitor using a pointing device.

If you have to wheel your mouse all the way across the screen to home in on a link, button, or menu title, Fitt’s law kicks in. But wheeling over to a corner is super easy, requires almost no steering. And that’s why Hot Corners is so powerful. You have four easy to get to places on your screen, each of which can be assigned some specific function.

Read Zac’s piece, set up Hot Corners if you haven’t already. It’s worth it.
