@cindex overscrolling
If you're using Emacs on X (with GTK+ or Motif), you can customize the
variable @code{scroll-bar-adjust-thumb-portion} to control
@dfn{overscrolling} of the scroll bar, i.e. dragging the thumb down even
when the end of the buffer is visible. If its value is
non-@code{nil}, the scroll bar can be dragged downwards even if the
end of the buffer is shown; if @code{nil}, the thumb will be at the
bottom when the end of the buffer is shown. You can not over-scroll
when the entire buffer is visible.
