[NTG-context] MathTimes usage

[dr. Hans van der Meer]

I have the YandY MathTimes fonts and would like to use them in ConTeXt 
but do not know how to get them into action. In the source there are 
some references to MathTimes but nothing I try does something simple 
like for the lucida fonts:
     \setupbodyfont[lbr]
Maybe I missed the magic invocation for \setupbodyfont[MathTimes-magic]?

Hope someone can help.
