Two commands, don't know how abstruse that is:

:M	mark currently selected items to return
/	make some new selections
	[ ... more selections, deselections, etc. ]
	[ optionally read current set of selections ]
Y	Yank back initial set of selections

Hmmh - perhaps you could tell trn you have an infinitely tall screen,
then tell your screen client to log output to a file, tell trn to
display the thread-titles, capturing them to a logfile, turn off
logging, reset the screen height, and grep the logfile.
