ntg.nl/msg53524.html, Wolfgang saysthat we can use the pre-60 module. 
So I tried this snippet:\usemodule[pre-

\FlushStep\item three \FlushStep\stopitemize\StopSteps\stoptextBut it

12pt is loaded!LuaTeX error: There should have been a lua <node> here,
not an object with type string! ==> Fatal error occurred, no output PDF
file produced!Is there something broken in recent release of conteXt? 
By the way It seemsthere is no Rawsteps module anymore but it still is
in the wiki. Is there issomething like a bugtracker for conteXt, in
order to signal when  a feature isnot working or outdated and signal
when it is back (or definitly depreciate)?(it would be a complementary
tool for the mailing list) > > >

I'm following on an old thread about the RawSteps Module, which is
broken in MKIV. Trying to move to MKIV, this is a "no go" for me since I
absolutely need this module for teaching. I've contacted David Munger,
the author of the module,  last September, which had been a real helper
in the past about this module, but he has presently no time to work on
this. If someone know how to fix the problem, I provide a short minimal
exemple:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \enableregime[utf] 
\usemodule[rsteps]

\setupcolors[state=start] \setuppapersize[S4][S4]

\starttext

\StartSteps \startformula 
 \eqalign{ P[\text{atteindre l'état}\ j | \text{partant de } i] 
  & = P\left[\bigcup_{n=0}^\infty (X_n=j)| X_0 = i\right]\cr
  & \leq \sum_{n=0}^\infty P[X_n=j|X_0=i]\cr 
  & =\sum_{n=0}^\infty P_{ij}^n =0 \cr } 
\stopformula \StopSteps

\StartSteps \startformula
\eqalign{
  \FromStep[1][reserve]{P[\text{atteindre l'état}\ j | \text{partant de } i]} &
  \FromStep[1][reserve]{= P\left[\bigcup_{n=0}^\infty (X_n=j)| X_0 = i\right]}\cr &
  \FromStep[2][reserve]{\leq \sum_{n=0}^\infty P[X_n=j|X_0=i]}\cr &
  \FromStep[3][reserve]{=\sum_{n=0}^\infty P_{ij}^n =0 }\cr } 
\stopformula
\StopSteps

\stoptext

Also, here is the contextHarden link:

If somebody know another solution to show content by step in a page, I
would be happy to know about it. Thanks, Fabrice.
