[Tex/LaTex] Long section names in beamer document: headers and section transitions

beamertitles

I have long titles for mi sections in a beamer document and they take a long size of the header where I have the index. I have named them with a short name and a long name.
In both the header and the transition of each chapter they apperar the short titles, however I want the short version in the header and the long version for the transition of each section.

\documentclass[xcolor={dvipsnames},10pt]{beamer}

\setbeamercovered{transparent}

\usetheme{Darmstadt}

%---------------------------------------------------------------------------------%
    % Transition with the name of the section
\AtBeginSection[]{
  \begin{frame}
  \vfill
  \centering
  \begin{beamercolorbox}[sep=8pt,center,shadow=true,rounded=true]{title}
    \usebeamerfont{title}\insertsectionhead\par%
  \end{beamercolorbox}
  \vfill
  \end{frame}
}
%----------------------------------------------------------------------------------%



% For colors
\usepackage[dvipsnames]{xcolor}
\usepackage{amsmath}
\usepackage{xfrac}
% For columns
\usepackage{multicol}
\usepackage{biblatex}

%---------------------------------------------------------------------------%
%--------------------------%
% To add enumeration index

\addtobeamertemplate{navigation symbols}{}{%
    \usebeamerfont{footline}%
    \usebeamercolor[fg]{footline}%
    \hspace{1em}%
    \insertframenumber / \inserttotalframenumber 
}
\setbeamercolor{footline}{fg=black}
\setbeamerfont{footline}{series=\bfseries}

\usepackage{remreset}% tiny package containing just the \@removefromreset command

\setcounter{subsection}{1}

Best Answer

\insertsectionhead will give you the section name as in the header. To get the long version, use \insertsection

Some comments about your code:

  • It makes no sense to use use \setbeamercovered{transparent} if you later overwrite it with \setbeamercovered{dynamic}

  • unless you specify otherwise, beamer frames are vertically centred by default, so you can remove the \vfills from your section page

  • \usepackage[dvipsnames]{xcolor} is already loaded by beamer

  • \usepackage{multicol} is unnecessary beamer has its own column mechanism

  • \usepackage{remreset} is obsolet

  • don't mess with formatting instructions in arguments of macros like author or title, use \setbeamerfont{title}{size=\large, series=\bfseries} and \setbeamerfont{author}{series=\bfseries} instead

  • manual spacing instructions like \vspace{5cm} don't make sense in the preamble

\documentclass[xcolor={dvipsnames},10pt]{beamer}


%\setbeamercovered{transparent} useless as it is overwritten by dynamic
\setbeamercovered{dynamic}

\usetheme{Darmstadt}

% Transition with the name of the section
\AtBeginSection[]{
  \begin{frame}
  %\vfill
  \centering
  \begin{beamercolorbox}[sep=8pt,center,shadow=true,rounded=true]{title}
    \usebeamerfont{title}\insertsection\par%
  \end{beamercolorbox}
  %\vfill
  \end{frame}
}

%\usepackage[dvipsnames]{xcolor} % already laoded by beamer
%\usepackage{multicol} % unnecessary
%\usepackage{remreset} % obsolet

\setbeamerfont{title}{size=\large, series=\bfseries}
\title{Title}

%\vspace{5cm} %Makes no sense in preamble

\setbeamerfont{author}{series=\bfseries}
\author{Author 1}

%\vspace{0.15cm} %Makes no sense in preamble

\begin{document}

\section[Section 1]{This is the long title for the Section 1}
\section[Section 2]{This is the long title for the Section 2}
\section[Section 3]{This is the long title for the Section 3}

\end{document}
