Hi Uschi,

I use the MetaFun features of ConTeXt to cross out stuff.

% Cancel command for use in equations.
\startuniqueMPgraphic{cross out}
  picture cross;
  cross := image(draw (0,0)--(1,1); draw (0,1)--(1,0););
  draw cross xscaled \overlaywidth yscaled \overlayheight withpen pencircle scaled .8pt ;
\stopuniqueMPgraphic

\defineoverlay[canceloverlay][\uniqueMPgraphic{cross out}]

\define[1]\cancel{%
  \ifmmode
    \mframed[background=canceloverlay, frame=off, offset=overlay]{{#1}}%
  \else%
    \framed[background=canceloverlay, frame=off, offset=overlay]{{#1}}%
  \fi%
}

\starttext

\dots E.g.~$\cancel{x+ {-x}}$. Works in \cancel{text}, too.

\stoptext

I do not have all of the features of the “cancel” package, but it works for a simple cross out. Change the MetaPost code to a single slash, if that is what you want, by removing either one of the draw commands.

Hope that helps. If you need more features, I’d might be able to help you implement them.

Gavin
