Without a doubt the feature of help on a completion group is cool.  Those
numbers do fall into the category of a relative frame index. And there's an
absolute frame index,
a breakpoint number, and so on. And some of the categories are already
 built in like files.


But as with all things zsh-specific, I find it hard to get to to work on my
own.

I've been working on zshdb recently not for any specific need, but because
I have a little time right now to spend and over the years people have +1'd
it during the times when I didn't have time to devote to it.  (So a general
hint to users - if you +1 a project it will tend encourage maintainers of
the project to work on it.)

The debugger completion code I have is at
https://github.com/rocky/zshdb/blob/master/lib/complete.sh in case folks
want to improve it. You can run it standalone.
