Now under Assignment, select "Mouse Wheel Up".

The Auto repeat pull-down will appear. The auto-repeat pull- down will let you control how fast you'd like to send the mouse wheel up event or even a keystroke event. This will allow you to configure the rate that best meets your requirements. Experiment with various rates to see which one feels best.

Do the same steps for "Push Down" and set that to "Mouse Wheel Down".
