Of course. I use unmatched delimiters so infrequently that I forgot about it. Math fences replace most of the functionality of my old mathsets module. The only missing feature is the text key, but that is a specialized use case, so I'll just update mathsets so that it uses math fences in the background. I it really necessary to use Unicode characters to specify left, right, etc? I ink that most math users will be more comfortable using literal symbols, {,[,(,|, etc or tex names \Vert, \vert, etc. Aditya ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
