Active screen corners in Apple Mac OS X

Mac OS X is rocking a useful feature called hot corners, that can help you speed up your work.

If you point your mouse cursor into one of the four corners of your screen an action gets triggered. This only works if you have hot corners enabled.

If I point my cursor into a upper left corner, a Mission Control gets launched, displaying my opened programs and apps.

Let's see how to configure hot corners on your Mac.

Click to launch System Preferences.

Click Mission Control icon.

Click Hot Corners...

Now you see for choosing fields, each one represents a corner of your screen. In my case if I point my cursor to an upper left corner, Mission Control launches, if I point my mouse into a bottom left corner, I get my Desktop reveled and so on.

Just choose the settings on all of your four corners of the screen.

I'm going to change the setting for my bottom right corner to Start Screen Saver, name says it all. From now on, when I point my mouse cursor into bottom right corner, it will bring the screen saver up.

Click OK when you're done choosing the settings and that should be it.
