Document Classes ⇒ Header/footer in Beamer frames

[svend_tveskaeg]

Hi all.

On the TeX Stack Exchange I just read the thread Section numbering in Beamer ('CambridgeUS' theme). After testing the solution given[*], I am puzzled about one thing: Why is there parentheses to the left in the footer and what how so I use them for something meaningfull?

[*] See below:

Code: Select all

\documentclass{beamer}

\usetheme{CambridgeUS}

\setbeamertemplate{headline}
{
  \leavevmode%
  \hbox{%
  \begin{beamercolorbox}[wd=.5\paperwidth,ht=2.25ex,dp=1ex,right]{section in head/foot}%
    \usebeamerfont{section in head/foot}\thesection.\ \insertsectionhead\hspace*{2ex}
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.5\paperwidth,ht=2.25ex,dp=1ex,left]{subsection in head/foot}%
    \usebeamerfont{subsection in head/foot}\hspace*{2ex}\insertsubsectionhead
  \end{beamercolorbox}}%
  \vskip0pt%
}

\begin{document}

\section{The First Section}
\subsection{The First Subsection}

\begin{frame}
Test frame one.
\end{frame}

\subsection{The Second Subsection}

\begin{frame}
Test frame two.
\end{frame}

\section{The Second Section}
\subsection{The Third Subsection}

\begin{frame}
Test frame three.
\end{frame}

\end{document}

Thank you in advance!

PS. I haven't got a user account on the TeX Stack Exchange, which is why I write here.
