Wait, I use _all_ the widgets of scroll-bars, I don't "prefer" arrows
or any of them, they're all useful depending on the list.  For
example, when you have a large list with 10K lines in it, arrows are
not going to get you two-thirds the way down by sundown, so that's
when I would grab the "thumb" to get me close, then use the arrows for
fine positioning...

Why?  That small is hard to use...
