If you hover the mouse over a particular matching entry, it is
highlighted. I would like to be able to then pick up delete key press
and know which matching entry was highlighted.

Both had crossed my mind. I don't like the first, because it seems
very cumbersome in comparison to the solution I would like. However
this is the only solution I currently know how to implement. The
second solution would be very annoying, as many users, having seen the
word they want is not suggested, press delete to clear extraneous data
from the entry, and would thus probably also delete a matching entry
they would have wanted to keep.

Indeed. This is what I have been failing to make work.

Thanks for the suggestions.
