Hi Hans,
I have the following sample:
\setuptyping[option=TEX]
\starttext
\starttyping
\input zapf % knuth
\stoptyping
\stoptext
The percent character is in bold font and gray color, but the rest of
the commented text isn’t.

Many thanks for your reply, Wolfgang.
After reading the document, I think it could be achieved with:
\definefontfamily[mainface][mono][DejaVu Sans Mono]
\setupbodyfont[mainface]
\defineprocessor[myescape][style=bold,color=gray, left=\%]
\setuptyping[TEX][escape=myescape->{\%}]
\starttext
\startTEX
This is a c%omment.
% And this is another one.
\command
 [with colored]
 {brackets}
\stopTEX
\stoptext
But this doesn’t work. I must be missing something obvious.
What am I doing wrong here?
Many thanks for your help,
You have to add a comma after \letterpercent. You should also be careful with
the text in the comments because commands are expanded, e.g. take a look
at the \TeX in the comment.

\setupbodyfont[dejavu]

\defineprocessor[myescape][style=\ttbf,color=gray,left={\letterpercent}]

\setuptyping[TEX][escape=myescape->{\letterpercent,}]

\starttext
\startTEX
This is \TeX\ code % and this is a \TeX\ comment.
\stopTEX
\stoptext
