[Tex/LaTex] Find out what symbol enumerate is using

Question

I'm working on a poster in beamer. The style uses

\setbeamertemplate{enumerate items}[circle]

which generates a number inside a circle as the symbol for items in enumerate. I'd like to reference an item in my enumerated lists later on the poster (in the middle of a sentence), but I can't figure out how to generate the same symbol that enumerate is using. How can I check?

Answer 1

Here's one way to do it using a \Myref command (the original definition for the circle template can be found in beamerbaseauxtemplates.sty):

\documentclass{beamer}
\setbeamertemplate{enumerate items}[circle]

\newcommand\Myref[1]{%
  \begingroup
  \usebeamerfont*{item projected}%
  \usebeamercolor[bg]{item projected}%
  \begin{pgfpicture}{-1ex}{0ex}{1ex}{2ex}
    \pgfpathcircle{\pgfpoint{0pt}{.75ex}}{1.2ex}
    \pgfusepath{fill}
    \pgftext[base]{\color{fg}\ref{#1}}
  \end{pgfpicture}%
  \endgroup
}

\begin{document}

\begin{frame}

A cross-reference to item~\Myref{test}.
\begin{enumerate}
\item A test item
\item Another test item\label{test}
\item Yet another test item
\end{enumerate}
\end{frame}

\end{document}
