Until now I had understood this as if you put symbols near marks to refer 
to certain (marked) points of the diagram in the text nearby. I was about 
to explain that you could "combine" labels with marks by


or more sophisticated ... This came from the thread name `Combing symbols' ...

Now however it seems to me that you don't want to combine anything, just 
center something on a coordinate. This really should not be done by 
shifting ..., but by


or with lowercase letters perhaps, according to my previous posting,


My TLC1 (German) p. 289 seems to tell me that it is standard to center
