which command would give the same effect as \pause in beamer ?

[damien@thiriet.web4me.fr]

Hello,


I have been switching to conTEXt to prepare some of my teaching stuff. I have read the context ref manual, the wiki and browsed the web, but couldn't find anything related to so-called overlays in beamer (I justed greped mail archives for 2015–2017).
What would be the conTEXt way to have a list or whatever else displayed in a slide in such a way that point 2 is hidden until you press space, and so on.
In beamer, you would make it this way

\begin{frame}
   \begin{itemize}
      \item 1 
      \pause
      \item 2
      \pause
     \item 3
\end{frame} 

Or even better, 

\begin{frame}
   \begin{itemize}[<+->]
      \item 1 
      \item 2
     \item 3
\end{frame} 

I read about \starthiding and \stophiding in the manual, but as far as I understand, this is not exactly what I am looking for.
I don't think postponing would help either.

Any suggestion will be welcome. I am using texlive 2015 version (nothing newer is available yet in OpenBSD). 
Have a nice day,


Damien Thiriet
