> Why on earth would anyone implement a scrollbar that used more then one button?

Because a click on one button does a page down operation toward the tail
end of the document and a click on the other button does a page up
operation to move toward the top of the  document.

In my case, at least, I do not always want to scroll forward; sometimes
I want to back up.  And I would like to be able to scroll forward
sometimes by a little bit and sometimes by a lot.

On my favorite editor a click on the left button scrolls forward by the
distance between the top of the window and the place where I click.  A
click on the right button goes the other direction.  As a result, I can
leave the mouse in one place and move about the document.

(I have a real problem with scroll bars which reverse direction just
because the elevator image has moved past the mouse.  All of a sudden
the clicks I was using to move toward the tail end of the document are
now moving me in the other direction.)
