Sorry I wasn't clear. I assumed too much. I spent an entire weekend working through this stuff at the start.
typescript/font mechanism is far too high for me.
Patrick, nearly everything I knew about fonts in ConTeXt was learned from Bill McClain's excellent resource: http://home.salamander.com/~wmcclain/context-help.html
I have visited this page again. I guess I have to put it under my pillow and read it every evening. Perhaps one day I know how to... I've got it working now. Thank you very much. One thing I'd like to comment: i think tat rscale=1.1 for cmtt is a bit too large.
Basically, you put this into one file, say "font-ttt.tex":
That is what I had before, but somehow I could not make context to switch to that font. Since I don't know how to debug this stuff, this is either "get it right" or "get it wrong".
I haven't been clever enough to figure out how to include the typescript in the same file that I'm ConTeXting.
That took me some time to discover...
My guess is that this is because of a (reasonable) assumption of wanting to reuse typescripts.
Hans should know.. :)
I hope that's of some help, even though it's yet another example.
Well, a clear definiton of how typescripts work would be nice. But Bill has a lot of comments as far as I have seen. Thanks again, Patrick
