Hi Urs,

Many thanks. You seem to have cut the knot I had.

So, Both are setting a property but the difference that they are for
different kind of Objects...

And a big question, could it be that \set and #(set are the same or is
it different thinks? I found them sometime in a interchangeable matter.

Hmm.. Yea, maybe.

Currently I just use settings from the examples and try to get them to
work properly.

Seeing my problems I had with the layout in my past mails, I try to
figure out what went wrong and how to solve it. Ending in the swamp of
internals that I do not understand. :-O

Thanks, I think, it helped some.
