I'm on a laptop without a mouse. This means I don't have the middle mouse button/wheel. I tried to use ahk to make my numpad act like a mouse wheel with the middle mouse button. Numpad8::WheelUp Numpad2::WheelDown Numpad5::MButton The problem is that it scrolls up/down 2 times (when I click and release the button). How do I make the wheel scroll only once when I hit the button and not again after releasing it?
