One thing I use AHK for: I bought a logitech trackball, which is great for my RSI, but unfortunately it has no scroll wheel/button, and man, life without scroll wheel and middle click is just impossible! Luckily, it has 4 buttons apart from the ball, so someone wrote a script to make use of one of those buttons together with the ball to provide the scroll wheel / middle click experience, and posted it on the forums. Really great that a tool like this exist for this kind of situations.
