Therefore, 10 clicks should equal 20 lines. At a low 'Scrolling Speed' as per the Mouse CP option it does about 2 lines per click. When I move my mouse wheel, I can hear it click slightly as it moves to the next position. I want to disable Maverick's built in scroll wheel acceleration. I want it to always be 2 lines at a time. Two lines at a time become 20 lines at a time. Currently, if you rotate the wheel fast, it accelerates. I am talking about the amount of lines my screen scrolls when I roll the scroll wheel on my mouse. I am not talking about mouse pointer speed acceleration. How do I disable my Mouse's Scroll Wheel Acceleration in Mavericks?
