I like the active/hot corner feature on mac's. This feature triggers an action in case user places mouse pointer into a corner. So 4 different actions can be defined. Note that when you repeat the mouse movement to the same corner the everything will be as it was before.
I like the most
show all open applicationsfrom which I can make one of them active.
Is there any equivalent to this on Windows (Windows 7)? I particularly want to access desktop and see all open applications.
