I had Synergy set up so that in order for my cursor to cross over into another computer, I had to double-tap the edge of the screen with the cursor.
I would like to replicate this behaviour within a single system with three displays attached. In other words, I would like to bind my cursor to the current display, and have it move to a neighbouring display only when I double-tap the edge. This would make corner buttons, like the start and show desktop buttons, easy to reach again, while (hopefully) enabling aero snap to the edges of every display.
How might I go about accomplishing this?
