Question

Beamer navigation bar with sections ans SUBsections but without SUBSUBsections?? I'm using PaloAlto theme.

Answer 1

You can set the beamer templates subsubsection in sidebar and subsubsection in sidebar shaded so that they don't insert the subsubsection title:

\documentclass[a4paper,11pt]{beamer}
\usetheme{PaloAlto}

\makeatletter
\setbeamertemplate{subsubsection in sidebar}
  {\vspace*{-\baselineskip}}
\setbeamertemplate{subsubsection in sidebar shaded}
  {\vspace*{-\baselineskip}}
\makeatother

\begin{document}

\section{test section one}
\begin{frame}test\end{frame}
\subsection{test subsection one}
\begin{frame}test\end{frame}
\subsubsection{test subsubsection one}
\begin{frame}test\end{frame}
\subsubsection{test subsubsection teo}
\begin{frame}test\end{frame}
\section{test section two}
\begin{frame}test\end{frame}
\subsection{test subsection two}
\begin{frame}test\end{frame}

\end{document}

Here's the first frame of the resulting document, showing the sidebar without the subsubsection titles:
