Hi Fabrice,

I have this from former exchanges

% 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%
}

Maybe something else is available nowadays.
