While Bob's specific need was in fact met by setting the item delimiter and 
using "last", I concur with his call for a general method for seeking in 
reverse.  It's not that it's hard to code, but it would be trivial* to 
implement it directly in the engine, and that would be very much faster than 
the transcript version.

There's a proposal in bugzilla for this:

Please consider tossing it some votes...


*trivial: usual caveats apply
