Interesting how too much familiarity with a language makes a fella forget
the occassional "lack of orthogonality".   I'd certainly not thought about
this one in a while, but I agree the magic token is unobvious.  ;)

You're right, focusOut is the right message for _most_ objects, but unlocked
fields are an exception.  For those, if the data has changed you get the
closeField message as you've found.  If the data has not changed you get the
exitField mesages

Given that exitField is such an anomaly in an otherwise fairly
self-consistent language, maybe the only way you might hae discovered it is
in the See Also section of the Transcript Dictionary, as useful source to
keep in mind while you're learning.
