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).

Hmm, this works, but duplicates the above definition.
If I don't want to use > as prefix but ›, I need to replace it in two places.
