   Does anyone know how to make "highlighting" of presentations in the form
   of a cursor that tracks the pointer along the length of a presentation?
   I presume that tracking-pointer and highlight-applicable-presentation
   are involved, but lacking any examples of how they work, I am
   floundering.

   I am currently doing this in Clim 1.0 under Lucid, but should be able to
   upgrade if necessary.

Bill,

it sounds like (i'm not sure) you want to highlight a presentation
such that the highlight is somewhat animated while the pres is
highlighted -- perhaps a cursor following the cursor inside the
highlight?  I don't know how you can do this with redefining
clim:highlight-presentation, since I believe it is only called once
(when the pres is scrolled on).  it sounds like you may have to use
tracking pointer, check to see whether a presentation is highlighted,
and draw a pointer-following glyph.  Is this occurring in some subset
of the overall user activity?
