Nice solution. Not fool-proof either: you need to know beforehand when 
to try and ush TAB a second time; but probably ok. Ideal would be a 
pop-up menu presenting all possible choices; the difficult part being 
how to represent the choices so that one can easily find out which 
corresponds to what one wants, and still manage to keep them to less 
than a screenful of code ;-)
