How do I rename tracks in Rhythmbox?

[Neil Woolford]

I've ripped some CDs to .ogg with Sound Juicer.  The results are
excellent, even off CDs that skip badly in an audio player.

However, not everything comes through with meaningful track labels;  it
seems to depend on how the original CD was mastered.  Some have
meaningful track names after ripping, others just have Track 1, Track 2
etc etc.

I'd like to edit some of these placeholder names into full track names,
but I can't find how to do it.  I can easily find a 'Preference'
dialogue and even highlight the track name in it, but I can't edit it.
