just to get you some (wikiable) ideas:

\startreusableMPgraphic{return}
    drawarrow
      (0,0)--
      (1EmWidth,0)--
      (1EmWidth,-.5ExHeight)--
      (.5EmWidth,-.5ExHeight) ;
\stopreusableMPgraphic

\definesymbol[return][\reuseMPgraphic{return}]

\setupcolors[state=start]

\starttext

\def\vcrlf{\symbol[return]\crlf\strut\kern1em\strut\ignorespaces}

\setuptyping[option=commands]

\starttyping
test test test /vcrlf test test
\stoptyping

\setuptyping[option=color]

\installnewpretty r \vcrlf

\starttyping
test \test{test} %%\ r test test
\stoptyping

\stoptext
