while we are at it: how to do do strikethrough text? there is a changelog on contextgarden which says it was added, but \strike or \strikethrough are not defined.
i have (a diagonal) one here, but it doesn’t really work in math mode (the text inside is normal). that being said, is there something like \ifthiswascalledinmathmode{then}{else}?
\def\strike#1{\tikz[baseline=(c.base)]{
\node[inner sep=0pt] (c) {#1};
\draw (c.south west) -- (c.north east);
}}
