Indeed… ConTeXt is so rich! Probably I use only one or two per cent of its 
capabilities, but still I am happy and often amazed…

Hi Fabrice,

Do you know the step charts module in ConTeXt? I guess you can achieve what you 
want as in the example below (sorry, I did not took your example, I am just 
copying an example from my archives…).

%%
\usemodule[steps]
\starttext

Pour voir que la composée de deux fonctions $f$ et $u$, continues en un point 
$x_{*}$, est continue, on peut suivre le schéma suivant~:
\placefigure[middle,none][-]{}{
%\scale[,width=.35\textwidth]{
\startSTEPtable 
\cell {$(f\circ u)(x_{*} + o(1)) = $} \text{définition de $f\circ u$}
\cell {$f\left(u\left(x_{*} + o(1)\right)\right) = $} \text {$u$ est 
continue} 
\cell {$f\left(u(x_{*}) + o(1)\right) = $} \text {$f$ est continue} 
\cell {$f\left(u(x_{*})\right) + o(1) =$} \text {définition de $f\circ 
u$} 
\cell {$(f\circ u)(x_{*}) + o(1)$.} 
\stopSTEPtable
%}
}
\stoptext
%%
