i've got an -in itself interesting- trick to visualize this in color; i'll
send you an example off-list. [i can post it at our site if there is more
interest in it]; also, when such a tool is needed, and you are willing to
install context to visualize efcode settings, i can clean/document up the
tex code and put it into a module (rather trivial code btw once you know
the trick).
