Wolfgang and Rik Thank you very much. This was exactly what I needed. I'll add these to http://wiki.contextgarden.net/Fonts_in_LuaTeX Michael

You can find a description about the options in the old and new fonts manuals:

Font definition in ConTeXt allows extreme degrees of indirection. There is a lot of flexibility that follows from this. By defining synonyms such as serif and serifbold and using these in the document, the document can be written independently of the actual fonts used. The names are to some degree arbitrary, but used conventionally. There is nothing stopping you from placing a sans font at the end of a chain of serif references. Rik
