It does; and it sounds quite interesting.

Why don't you add another hidden field (or bunch of hidden fields) tagged
with PROP_DONT_SAVE (so that they are gone once the file is saved/reloaded),
and temporarily hold the state of your BiBTeX dialog into those new hidden
fields? (also, why do you want to hide the keyword field? Wouldn't it be
better to let the user see the what the keyword is right into the main
property dialog, and then click on the button if s/he wants to change it?)
