I think Mac people become fixated on the latest new features and capabilities of the macOS. Because of that, we tend to overlook the tried and true features that have been in the macOS for years, features like Hot Corners. If you are looking for a quick way to execute certain commands on your Mac Desktop, Hot Corners is a nice way to go.
This is all by way of reminder, I am sure most of you have known and used Hot Corners at times. Just for reference, the Hot Corners feature allows you to move your mouse to one of the corners of your Display to activate some type of action on your Mac. In Big Sur, Hot Corners are located in the Mission Control Preference Pane area.
Once inside this window, click on the “Hot Corners” button in the lower-left corner.
Now you are in the Hot Corners menu area.
I have “Put Display to Sleep” and “Start Screen Saver” setup for two of my Hot Corners. To create a Hot Corner action, just click on the dropdown and select the activity you wish to perform.
Each dropdown menu corresponds with that corner of your screen. That is all there is to it.
It is straightforward to set up Hot Corners. I am sure you can find an action or two from the dropdown list that would be useful.
