Nevertheless, I prefer to keep all the font and fontsize definitions and 
tweaks together in the preamble. This poster is not the only work I'm 
planning to do in ConTeXt, and I need to learn to swim while already in 
the water ;) .

Meanwhile I found the command \definebodyfontswitch and defined switches 
like \normalsize, \scriptsize, \large, \Large etc.

But this doesn't explain why \definebodyfontenvironment did not do 
anything in my MNWE. The fonts book is not very clear on its intended use.

BTW, I have no idea how all the strange line breaks crept into my code 
sample again. It seems tabs in a html mail are converted into line 
breaks somewhere along the line. I'll stick to plain text in the future.

Cheers -- Thomas
