That works fine for the particular case I was thinking of, and maybe with some slight changes I can deal with some other similar cases in ConTeXt. One question of possible interest to people on this list... So far I've submitted some changes after submitting bug reports. If one wishes to do an "enhancement", is there a non-bug-report path for that? (But, it is is easier, I can always submit a bug report about missing functionality.) Cheers. Jim
