Thanks Taco.  I'm sure I'll get the hang of the new tabular commands
eventually - though reproducing the example on pp. 274-5 of the Not so
Short Introduction doesn't quite work (the second column is shifted a line
down from the first column - but I guess there's something I should have
set up initially to get it to work).

It's not the definition of \yogh that would cause me any difficulty, but
the fact that I can't say:

\defʒ

This works in plain (Xe)TeX after I've reassigned the \catcode of
\char"0292 to \active, but ConTexT grumbles that I must have a backslash
after \def, and when I try that the compilation still fails. No matter -
I'll figure it out eventually!

Best wishes
