i have looked at insertIndex() & removeIndex() but 
am still not sure how it works in my situation.  i am working
with just a simple sequence of chars (string) but i believe
 insertIndex() & removeIndex() applies more to lists/sequences
of objects.  but insertIndex() & removeIndex() seems to be very
interesting, maybe i missed something subtle there.
