Question

I have a long index (outline) for a presentation. Obviosly my index exceeds the size of a presentation page.

Is there a way to split a /tableofcontents in two columns?. This my code to generate the index.

\begin{frame}{Índice}
    \tableofcontents
\end{frame}

Answer 1

The solution is:

% preamble
\usepackage{multicol}

\begin{frame}{Índice}
\begin{multicols}{2}
  \tableofcontents
  \end{multicols}
\end{frame}
