    range: switch secondary and middle button on steppers
    
    Clicking on steppers does different things depending on which
    button you use. We used to scroll to the end on secondary click
    and use high-speed autoscrolling on middle-click. Switch these
    two around, since the scroll-to-end functionality is less likely
    to be useful, and the seconary button makes the autoscrolling
    more easily available.
