'changed' rather than 'change' is a confusing distinction. Events are usually
... imperative? infinitive?

I agree. I'm not sure where I got on-changed initially, but unfortunately that
is what I have been using in settings/internet. I have a cleanup CL following
this one where I will replace all 'changed' events with 'change' including this
one.
