Comment 8 for bug 881472

Styling or not, this is a major UI impedement for users without scroll wheels, like myself and the Logitech Trackman Marble. Being able to click the arrows to move up and down in small increments (especially in large lists) is a fundamental feature of the scroll bar which should not be disabled. I wish this sort of "choice" could be pulled out to the Appearance dialog instead of locked inside the theme files.

Thanks to Nokir for the "workaround".
