I've finally (I am a smalltalk beginner) been able to customize my
scrollbardispatcher so that I can use PgDn and PgUp to scroll up and
down, but this points out a problem in the implemetation.  Namely,
when you use the keyboard based scrolling methods (shift-up arrow or
my PgUp, for instance), the scroll bars are not updated to relect the
new position in the file.

Does anyone know what to fix for this?  When I tried to halt it during
scrolling with the mouse in the scroll bar (which IS updated
correctly), I got into a VerticalScrollBar class, but I updated foir
the keys in ScrollDispatcher.

What to do?
