# 3. Footer

It is quite common to add text (such as the presenter’s name, the presentation’s title, university, and more) to the bottom of one or more slides. The footer in Fig. 1 is corresponding the following code.

% footer
\makeatletter
\setbeamertemplate{footline}
{
\leavevmode%
\hbox{%
\insertshortauthor
\end{beamercolorbox}%
\insertshorttitle
\end{beamercolorbox}%
\insertshortdate
\end{beamercolorbox}%
\end{beamercolorbox}}%
}
\makeatother

For instance, insert a horizontal navigation bar containing all sections, with the current section highlighted.

\makeatletter
\leavevmode%
\hbox{%
\begin{beamercolorbox}[wd=\paperwidth,ht=2.5ex,dp=1.125ex]{palette quaternary}%
% Flush the bar to the left
% Flush the bar to the left
% Flush the bar to the center
\end{beamercolorbox}%
}
}
\makeatother

%% Usage
• left insert will be inserted to the left of the sections
• right insert will be inserted to the right.
• \hskip0pt plus1filll inserts a triple fill to flush the bar to the left/right/center.
