Making full use of four corners in OS X

The four corners of screen in OS X can be setup to be active “Hot Corners”, which will carry out defined task when the cursor is moved into a corner. To configure Hot Corners, open System Preferences and look under Mission Control.


Click on the button “Hot Corners…” at left-bottom of window, which will bring up the setup pane for the four active screen corners.


Select the task you would like to be activated when the cursor is moved into a particular corner. Click “Ok” button to save the settings. As an example, in the above screenshot, the left-top corner is defined for “Mission Control”. When you move the cursor to the left-top corner of the screen, Mission Control will be run. Test it out. You might prefer this way of activating Mission Control or Launchpad instead of using keyboard shortcut or the trackpad.
