What I probably want doesn't have anything to do with me. That's rather a
matter of other peoples guesses about me and not relevant for anything.

Great, that's exactly what I want.

I can't see any problems with that. Maybe I don't follow.

Yes, why would it do anything else than that?

Oh, I don't know anything about that. I only know I wouldn't, and if I did,
it would be my fault only. I'm not expecting Calc to do the thinking for me.

No, I'm rarely impressed when things just work as expected. They just

No, that's just wrong. Only absolute references (those with $-signs
everywhere) will be searched for, nothing else. Don't over complicate this

The one that Calc itself associates with the name, that is those with
$-signs everywhere. I actually finished my macro instead of making up a lot
It proved to be quite easy, actually:
You can easily get any used name and its corresponding reference (or
”address”) by index with:
For lNameIndex=0 To lNameCount-1
sAddress in this case always looks something like $SomeSheet.$A1:$B75.
Inside that loop I have another loop, that loops through all sheets. When
searching the same sheet as the Name is located, I also search for $A1:$B75
kind of reference.
It works great as far as I can tell, so far. Maybe I will run into
something in the future, who knows?
The only problem I saw so far is that at one point there was a reference
like this: $SomeSheet$A$1:$SomeSheet$B$75, that is with the sheet name on
both sides of the colon. I'm not sure how that could happen. I'm pretty
sure I didn't type that and so far I found no way to make Calc doing that,
so I'm not sure what went wrong there. Maybe it was me after all. The macro
seems to be very fast anyway, so I guess I could make it take care of that
kind of reference as well with reasonable speed.

I tried to assign a name to such a reference, but Calc didn't like that
very much… I get Error 522 (circular reference) every time I try to use the
name. Maybe it's a bug.

The last one is not valid (#NAME?), so not a good example.
