Your MacBook has lots of hidden features that you will never know. Hot corners is one such feature very useful to assign functions to any four corners of your Mac. You can simply move the mouse over to the corner to activate the function. For example, you might be familiar with Windows 10 show desktop button on the lower right corner of the taskbar. If you miss that button, you can easily have a similar setup in Mac as well using hot corner.
How to Setup Hot Corners?
Click on the Apple menu and go to “System Preferences…” option. You will see lots of icons along with your Apple ID details.
Click on “Desktop & Screen Saver” option and go to “Screen Saver” tab. You will see “Hot Corners…” button on the bottom part as shown in the below picture.
Click on the button to open a pop-up. You will see four dropdown boxes indicating the four corners of your Mac.
Basically, you can assign same or different function for each corner. Click on one of the dropdowns to see the list of the available functions.
Hot Corners Functions in Mac
There are 10 different functions you can assign to the corners of you display.
- Start screen saver
- Disable screen saver
- Mission control
- Application windows (shows the highlighted application)
- Notification center
- Put display to sleep
- Lock screen
Using Hot Corners in Mac
You can select the function from the dropdown and click “OK” button to save the changes. Mac will activate the function automatically whenever you move the mouse over the corners. If you miss Windows show desktop button or lock screen options, then using hot corner can help you in Mac. You can select the same or different functions for each corner. For example, selecting “Desktop” option on all four corners will show the desktop when you move the mouse over any of the corners.
However, we recommend you to setup four different functions for each corner to make use of the feature effectively.
Setting Keyboard Shortcuts for Hot Corners
The problem with the hot corner is that it may interrupt in your workflow if you are frequently moving the mouse pointer towards one of the corners. For example, we use apps like sticky notes or one-click screen capture from Snagit on the top right corner. Also, by default, your Mac will have “Notification Center” nearer to the top right corner. In such cases, it will be embarrassing to get the hot corner function when you move the mouse just few centimeters. Don’t worry, you can also setup keyboard shortcuts with mouse movement for hot corner functions.
When clicking on the dropdown, press and hold one of the modifier keys. You can press and hold command, shift, option or control key. This will show the selected key in the dropdown menu against each item like below.
Now select the function and you will see the shortcut key is attached to it. In our example, we have assigned command key as a modifier for showing desktop to lower right corner.
Now, you need to press command key and move the mouse to lower right corner to show the desktop. This will avoid accidentally activating the function with mouse movement. You can assign any combination of the command, shift, option and control keys to activate the hot corner function. For example, you can assign “Control + Shift + Option + Put Display to Display” for lower left corner and “Control + Shift + Launchpad” to upper left corner.
