But that's not what I mean! I know that I can place
the key arbitrarily - IFF I know, in absolute terms,
where I want it!

My use case is this: I want to use the automatically 
chosen position as starting point, and then modify it.
This could be done through an "offset" directive in
"set key", but it could also be done if I could read
out the currently chosen key position from some 
automatically set GPVAL variable. But none of the
GPVAL vars seems to refer to the current key position.

Or am I missing something?
