Otared points out that the distinction between \triangle and \bigtriangleup comes from plain TeX. plain.tex has these definitions: \mathchardef\triangle="0234 \mathchardef\bigtriangleup="2234 So \triangle is a math ord and \bigtriangleup a math bin. For compatibility, that should probably stay true in ConTeXt too---even the low placement of \bigtriangledown, which I don't understand but which does reproduce plain TeX's placement. > Btw, it is still on my agenda to provide a mechanism for switching > between math dictionaries (i.e. group symbols in group switch if needed > different properties) so that one can switch between logic, > statistics, streetfighting or whatever math. Hm, like different dialects of a language. Plain TeX definitely speaks a pure-mathematician dialect. It would be interesting to see what symbol groups are useful in other dialects. -Sanjoy ___________________________________________________________________________________ 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 ___________________________________________________________________________________
