[Tex/LaTex] Reduce spacing in table of contents (beamer)

beamerspacingtable of contents

How can I reduce the spacing between the items of my table of contents in my beamer presentation?

Here is my currient LaTeX code:

\documentclass{beamer}
\usepackage[T1]{fontenc}
\usepackage{lmodern}der pdf
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}

\title[Short title]{My very long title that doesn't fit into the footer}
\author{Me}
\date{\today}
\beamertemplatenavigationsymbolsempty
\setbeamertemplate{footline}[frame number]
\usetheme{CambridgeUS}

\AtBeginSection[]
{
\begin{frame}
\frametitle{Outline}
\tableofcontents[currentsection, hideothersubsections]
\end{frame}
}

\begin{document}

\maketitle
\clearpage

\begin{frame}
\frametitle{Outline}
\tableofcontents[hideothersubsections]
\end{frame}


\section{Intro}
\begin{frame}
\frametitle{Welcome}
...
\end{frame}

\section{Topic 1}
\begin{frame}
\frametitle{Topic 1}
...
\end{frame}

\section{Topic 2}
\begin{frame}
\frametitle{Topic 2}
...
\end{frame}

\subsection{Red}
\begin{frame}
\frametitle{Red}
...
\end{frame}

\subsection{Green}
\begin{frame}
\frametitle{Green}
...
\end{frame}

\subsection{Blue}
\begin{frame}
\frametitle{Blue}
...
\end{frame}

\section{Topic 3}
\begin{frame}
\frametitle{Topic 3}
...
\end{frame}

\section{Topic 4}
\begin{frame}
\frametitle{Topic 4}
...
\end{frame}

\section{Topic 5}
\begin{frame}
\frametitle{Topic 5}
...
\end{frame}

\section{The end}
\begin{frame}
\frametitle{The end}
End of file :-)
\end{frame}

\end{document}

See page 7 the point "The end" is missing. I need that one.

The internal command \beamer@sectionintoc (defined in the file beamerbasetoc.sty) controls how the section entries will be typeset in the ToC; it issues a \vskip1.5em that adds vertical spacing between section entries. With the help of the etoolbox package you can easily patch the command to add less vertical spacing. A little example:

\documentclass{beamer}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{etoolbox}

\makeatletter
\patchcmd{\beamer@sectionintoc}{\vskip1.5em}{\vskip0.5em}{}{}
\makeatother
