A new key binding or several is an obvious solution. It's also the 
clunkiest one (one: key bindings are precious, two: that means extra key 
presses to use, and three: extra stuff for the users to memorize).

So of course we can fall back to this approach, but it would be great to 
discuss something less obvious first.

The error is not always near point, or even visible in the window. To 
get to it, we need a key binding. So, next-error or previous-error 
working already would be helpful.

That's a problem for another day, I think. Lists in the same buffer can 
probably be combined anyway.
