How to animate scrolling?

I have a moderately complex tree of morphs which I am tracing through,
highlighting each one as it is touched. Occasionally I need to scroll my
view to bring the next touchee into clear view. I'd like to do a nice
smooth scroll, but so far have failed miserably to get it to work.
I am using stepping to do the animation of the highlighting, but the
scrolling needs to 'take precedence' so that we get something like:-
step->find morph, highlight
step->find morph, whoops scroll a little
step->scroll a little
step->scroll a little
highlight
step->find morph, highlight
etc....
I tried making my smooth scrolling method use 'self world doOneCycle'
after each mini-scroll but that somehow managed to stop the main
stepping. Very odd!
