Object naming

[Alex Tweedly]

I think my head is melting :-)

I have a group called 'A'.

Inside A, there is a rect called "R" and also a group called "B"

inside B there is a rect called "R"

How do I refer unambiguously to the first rectangle (i.e. A - R, not A - 
B - R) ?

If I say
    grc "R" of grp "B" of grp A
then I unambiguously get A-B-R; but if I say simply
    grc "R" of grp "A"
then I *also* get A-B-R.

There must be a way to do this (and maybe if it wasn't nearly 2 in the 
morning I would be able to figure it out).

Help! Please !

Alex.
