[AUCTeX] labeled environments

[Andreas Matthias]

\documentclass[a4paper]{article}
\usepackage{lscape}
\usepackage{caption}

\begin{document}

\begin{landscape}
  \captionof{figure}{foobar}
  \label{fig:foobar}
\end{landscape}

\end{document}



In the above example the label if found with `C-c ) SPC' but
it is not found with `C-c ) f'. What do I have to do to let the
label appear with `C-c ) f'?

I tried to extend reftex-label-alist with

  (add-to-list 'reftex-label-alist ("landscape" ?f "fig:" nil nil 0))

but it doesn't work. I don't grok it. Can you help me?
