I played a little bit around with the above sample and thought that
putting a second '\' in front of the second argument for the \seeindex
command could help as it looks like the abbreviation \GCc looses the
backslash when the 'see' entry is generated in the registry.

As this was working I looked at the '.toc' file and saw that the key and
entry values are enclosed between [===[ and ]===] but the abbreviation
\GCc wasn't. I thought that maybe this works like an escaping mechanism
and changed the command \mksaveregistersee in core-reg.mkiv from

\def\mksaveregistersee#1#2#3#4#5#6#7% class type reference key entry
see pagespec
  {\expanded{\writeutilitytua{ti(jr['#1'],{'#2','#3',\!!bs#4\!!es,\!!bs#5\!!es,'#6','#7'})}}}

to

\def\mksaveregistersee#1#2#3#4#5#6#7% class type reference key entry
see pagespec
  {\expanded{\writeutilitytua{ti(jr['#1'],{'#2','#3',\!!bs#4\!!es,\!!bs#5\!!es,\!!bs#6\!!es,'#7'})}}}

and it worked. I don't know if this breaks something else and if I was
right with what
I thought but the register is now created correctly and I couldn't see
anything weird
going on.

Drazen
