Custom definition of a bodyfont (and using it)

[Maarten Sneep <maarten.sneep@xs4all.nl>]

Hi,

I'm trying to make my own headings, and it doesn't really come out the 
way I want. I'll describe what I'm trying to do, and maybe someone has 
something that can help me.

I'd like to have the chapter number really big, in a (light) colour in 
the background. The title should go over the number. If 
possible/needed, the number may end up (partially) under the text. I 
think I can get the positioning correct (in metapost/metafun if I have 
to), but defining the (huge) font in ConTeXt proves a hurdle I cannot 
tackle.

My attempts (copied rather directly from the manual) are below.

Thanks for your time,

Maarten

%% This generated no error, but not a really large font either
\definebodyfont[9pt][rm][tfe=LucidaBright at 36pt]
\definebodyfont[9pt][ss][fte=LucidaSans at 36pt]

%% after the following definition, TeX claims it cannot find
%% \MyChapNumLetter
%\definebodyfont[MyChapNumLetter][LucidaSans-DemiItalic sa 4]

%% this example also comes from the manual
\def\MyChapterHeadingCommand#1#2{\hbox to \hsize\bgroup%
	\setupframed[offset=.5em,frame=off]%
	\tbox{\framed{{\color[MyChapNumColor]{\fte\ss\bf #1}}}}%
	\tbox{\framed[width=8cm,align=right]{{\tfa\ss\bf #2}}}%
	\egroup}
