     Right.  The lower you go, the less help you get from the
layers you've bypassed, and hence the more you've got to do for
yourself.  Kedward, consider yourself lucky to be handling
DocumentEvents instead of keyboard interrupts ...

     Sounds good to me.  Might not want to populate the ComboBoxModel
when there are too few characters to keep the possibilities to a
reasonable limit (I imagine that's why he specified three).  A more
flexible approach might take the number of matches into account
along with the prefix length, something like "Populate the model
when there are fewer than M matches, or when the prefix holds N
or more characters."  That way, ZBIGNIEWSKI and ZORRO could pop
up as soon as Z was pressed, while STI might wait for more input
before trying to display STIBICH, STICH, STICHTER, STICKELS,
STICKMAN, ..., STIVER, STIVES, STIX, all umpty thousand of 'em.
