How To Change Scrollbar Action In GNOME 3.10

I am using Ubuntu GNOME 14.04 which includes GNOME 3.10.

I would like to change the default method / action xwindows takes when I click on a scrollbar above or below the slider.

Currently it moves to the position in the file / object that corresponds to the point on the slider where you clicked. IMHO, this makes the slider button redundant.

I would prefer that the window behave as though I have hit page up or page down on my keyboard.
