Hi,

I was in the process to convert an itemize part to a description and wanted to 
simplify the code in the same move.
I discovered headcommand for that, but struggled to set the text in an 
highlight _and_ make a colon at the end.
Not sure what exactly you want, but how about:

\definehighlight[hl][style={\m{>}\,\switchtobodyfont[tt]}]
% This is the wrong way to define such a command as '>' is not part of the 
style. I have left this definition just for comparison with the soln below.
Is there a better way to define a highlight that sets a style (color, font) 
_and_ a prefix (symbol)?
Another way, I know of, would be just a plain def, something like 
\def{\hl}{\groupedcommand{>\,\switchtobodyfont[tt]}{}}, but actually I want to 
define a highlight (just with an additional prefix).

1. ConTeXt already uses \hl as name for a existing command.

2. Use \definestartstop:

\definestartstop [gerion] [style=mono,left={›\thinspace}]

\starttext

text

\gerion{text}

\stoptext

\definedescription[category][
        alternative=top,
        headstyle=bold,
        width=broad,
]

\definedescription[desc][
        width=fit,
        distance={\widthofstring{~}},

distance=\spaceamount,

Wolfgang
