+If you're using Emacs on X (with GTK+ or Motif), you can customize the
+variable @code{scroll-bar-adjust-thumb-portion} to control
address@hidden of the scroll bar, i.e. dragging the thumb down even
+when the end of the buffer is visible.  If its value is
address@hidden, 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.
