[Tex/LaTex] Enumerate label numbers

#enumeratebeamer

I have an enumerate list in this MWE.

\documentclass[]{beamer}
\usetheme{Madrid}
\setbeamertemplate{items}[circle]

\begin{document}

\begin{frame}
\frametitle{Example}
\begin{enumerate}
\item First one
\item Second one
\item Third one
\end{enumerate}
In the above list, 2 and 3 are what more important.
\end{frame}

\end{document}

I want "2" and "3" in the text to be the same as in the list, a blue solid circle with white numbers.

How do I do that? Thank you.

If the appearance is the only thing matters, then the following will do:

Code

\documentclass[]{beamer}
\usetheme{Madrid}
\setbeamertemplate{items}[circle]
\usepackage{tikz}

\newcommand\mynum[1]{%
  \usebeamercolor{enumerate item}%
  \tikzset{beameritem/.style={circle,inner sep=0,minimum size=2ex,text=enumerate item.bg,fill=enumerate item.fg,font=\footnotesize}}%
  \tikz[baseline=(n.base)]\node(n)[beameritem]{#1};%
}

\begin{document}

\begin{frame}
\frametitle{Example}
\begin{enumerate}
\item First one
\item Second one
\item Third one
\end{enumerate}
In the above list, \mynum{2} and \mynum{3} are what more important.
\end{frame}

\end{document}

[Tex/LaTex] latex beamer appendix numbering

This is so, because \insertsectionnumber is defined as (in the file beamerbasesection.sty)

\def\insertsectionnumber{\@arabic\c@section}

And \appendix doesn't change this;

\newcommand<>\appendix{%
  \only#1{\part{\appendixname}
  \addtocontents{nav}{\protect\headcommand{\protect\beamer@appendixpages{\the\c@page}}}}}

so the counter will appear using arabic representation.

You can change this, redefining \insertsectionnumber in the proper location:

\setcounter{section}{0}
\renewcommand\insertsectionnumber{\Alph{section}}

Perhaps you want to let \appendix do this change:

\documentclass{beamer}

\makeatletter
\renewcommand<>\appendix{%
\setcounter{section}{0}%
\renewcommand\insertsectionnumber{\Alph{section}}%
  \only#1{\part{\appendixname}
  \addtocontents{nav}{\protect\headcommand{\protect\beamer@appendixpages{\the\c@page}}}}}
\makeatother

\begin{document}

\section{test1}
\begin{frame}{\insertsectionnumber.~\insertsection}
 bal bla
\end{frame}

\appendix

\section{test2}
\begin{frame}{\insertsectionnumber.~\insertsection}
 bla bla
\end{frame}

\end{document}

[Tex/LaTex] Order items in enumerate environment automatically

Although LaTeX is not the best language for this sort of thing, here is a potential solution. It uses the pgffor package.

First, we load the pgffor package and define a counter that will keep track of how many items there are in our list.

\usepackage{pgffor}
\newcounter{SortListTotal}

Then, we define a command that will store the list items.

\newcommand{\sortitem}[2]{\expandafter\def\csname SortListItem#1\endcsname{#2}\stepcounter{SortListTotal}}

The first argument of \sortitem is the item's number; the second is the item text.

Now, we define a command to print out the list. This command also resets the counter, ready for a new sorted list.

\newcommand{\printsortlist}{\foreach\currentlistitem in{1,2,...,\value{SortListTotal}}{\item[\currentlistitem]\csname SortListItem\currentlistitem\endcsname}\setcounter{SortListTotal}{0}}

These commands are used as in the following:

\begin{enumerate}
\sortitem{3}{This is the third item.}
\sortitem{4}{This is the fourth item.}
\sortitem{1}{This is the first item.}
\sortitem{2}{This is the second item.}
\printsortlist
\end{enumerate}

Alternatively, if you want to specify the order after storing the items:

\makeatletter
\newcounter{SortListTotal}
\newcommand{\sortitem}[1]{\stepcounter{SortListTotal}\expandafter\def\csname SortItem\arabic{SortListTotal}\endcsname{#1}}
\newcommand{\printsortlist}[1]{\@for\currentitem:=#1\do{\item\csname SortItem\currentitem\endcsname}\setcounter{SortListTotal}{0}}
\makeatother
