It is a text font and it has ligatures and kerning informations, but they are not used in math. Doesn't use context for \mfunction a text font too? I thought so because it has kerning when used outside math: \starttext \mfunction{WAiff} $\mfunction{WAiff}$ \stoptext Also bad kerning in operator names is a nuisance. I don't think that the default result of \definemathcommand[VA][nolop]{\mfunction{VA}} is good looking. > in context you can do: > > \setupmathematics > [functionstyle=normal] > > which will use a box which then will trigger text fonts Yes, one workaround is to quit math mode. The other to use fonts in mode "base". But I would like to understand why workarounds are needed at all. -- Ulrike Fischer http://www.troubleshooting-tex.de/ ___________________________________________________________________________________ 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 ___________________________________________________________________________________
