Hi! Do any of you know of a way to set up two active corners so that they switch desktops? I would like the bottom left corner to switch to the desktop to the left of the current one and the bottom right corner to switch to the right. The effect I want is exactly the same as the three/four finger swipe left/right on the trackpad, but I would like a way to do it quickly when using my old-fashioned mouse. - Thanks in advance for any suggestions!
