He said the "vertical split bar."  Unfortunately all mouse clicks in
there are by default bound to scrolling (since it's a scroll bar,
pretty much, not a modeline), I think, if you use scroll-bars.

If you turn scroll bars off (M-x scroll-bar-mode), then you can drag
that.  If you have them on and you _very_ carefully drag, not on the
scroll part, but on the vertical one-pixel lines around the scroll
bar, you will get them to move the way you want.  (At least, I was
able to do so.)

If you can bind a mouse click in the scroll bar to
mouse-drag-vertical-line, then you can get it to work, but you'd have
to test to see if you had multiple vertical windows, I think.  If you
don't want to scroll ever, you might as well turn scroll-bar-mode off;
then you will be happy, I think.

I got this off GNU Emacs 20.7, not sure about other versions.
