Thank you for your comment!

Since Transience is an external product, I'd have to extend it externally.  
Hmm, I wish that was documented in "The Zope Book" :-/  It's also be 
somewhat "challenging" to implement a keys method--the only thing I can think
of is to extend the notify on add or delete methods to do housekeeping on the
keys before actually doing the user defined functions for notify on add or 
delete.  Sounds like a lot of work in comparison to just adding an already
existing keys method to the API.  I really don't want to have to manage a patch
unless it's added to Zope :-/

Best Regards,
