I can't remember the last time I had to resort to manually scrolling by clicking the scrollbar

In order of use, I scroll one click, middle-click and drag (Best for constant movement), use the dedicated keys, use arrows, or use vimium bindings (Which I try to avoid, because I'd prefer to not get used to non-CUA keybindings on programs I might have to use in other computers)

Dragging the scroll indicator is much faster than some of these. And more reliable. And easier to control than middle click and drag.
