beamerbookmarkshyperrefsectioning
I wanted to put section numbers in pdf bookmarks of a beamer document. But section numbers didn't show up. What is the problem?
\documentclass{beamer}
\hypersetup{
bookmarksnumbered=true
}
\begin{document}
\section{Hello}
\begin{frame}Test\end{frame}
\section{Beamer}
\begin{frame}Test\end{frame}
\section{World}
\begin{frame}Test\end{frame}
\end{document}
I'm using MikTeX 2.9.
Assuming that you're using hyperref already*, the documentation states:
Usually
hyperrefautomatically adds bookmarks for\sectionand similar macros. But they can also set manually.
The manual setting is performed using
\pdfbookmark[<level>]{<text>}{<name>}
where \part is level -1, \chapter is level 0, \section is level 1, ... It places <text> in the bookmarks and can be referenced internally (via a hyperlink) as <name>. Or, if you want to place it at a level relative to the current one, use
\currentpdfbookmark{<text>}{<name>}
\subpdfbookmark{<text>}{<name>}
\belowpdfbookmark{<text>}{<name>}
where <text> and <name> have similar meanings as before.
In the following MWE, hyperref creates sectional bookmarks for every unstarred heading up to secnumdepth and only the numbered, unstarred versions show up in the ToC. The starred versions, removed from the ToC by default, are included using some variation of \...pdfbookmark:
\documentclass{book}
\usepackage{hyperref}% http://ctan.org/pkg/hyperref
\usepackage{bookmark}% http://ctan.org/pkg/bookmark
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\begin{document}
\tableofcontents
\part{FIRST PART}
\chapter{First chapter} \lipsum[1]
\section{First section} \lipsum[2]
\section*{Second section} \currentpdfbookmark{Second section}{ch:1:sec:2} \lipsum[3]
\section{Third section} \lipsum[4]
\subsection{First subsection} \lipsum[5]
\subpdfbookmark{First subsubsection}{ch:1:sec:3:ssec:1:sssec:1}\subsubsection{First subsubsection} \lipsum[6]
\currentpdfbookmark{Second subsubsection}{ch:1:sec:3:ssec:1:sssec:2} \subsubsection*{Second subsubsection} \lipsum[7]
\subsection{Second subsection} \lipsum[8]
\currentpdfbookmark{Third subsection}{ch:1:sec:3:ssec:3} \subsection*{Third subsection} \lipsum[9]
\pdfbookmark[2]{Fourth subsection}{ch:1:sec:3:ssec:4}\subsection*{Fourth subsection} \lipsum[10]
\subsection{Fifth subsection} \lipsum[11]
\chapter{Second chapter} \lipsum[12]
\end{document}
For the inclusion of sectional numbers in the PDF bookmark panel, use the bookmarksnumbered option of hyperref:
\usepackage[bookmarksnumbered]{hyperref}% http://ctan.org/pkg/hyperref
The above MWE will then produce:
* If not, the bookmark package provides similar, stand-alone functionality for inclusion of PDF bookmarks in your document. In fact, hyperref suggests using it as improved bookmark organization.
This is so, because \insertsectionnumber is defined as (in the file beamerbasesection.sty)
\def\insertsectionnumber{\@arabic\c@section}
And \appendix doesn't change this;
\newcommand<>\appendix{%
\only#1{\part{\appendixname}
\addtocontents{nav}{\protect\headcommand{\protect\beamer@appendixpages{\the\c@page}}}}}
so the counter will appear using arabic representation.
You can change this, redefining \insertsectionnumber in the proper location:
\setcounter{section}{0}
\renewcommand\insertsectionnumber{\Alph{section}}
Perhaps you want to let \appendix do this change:
\documentclass{beamer}
\makeatletter
\renewcommand<>\appendix{%
\setcounter{section}{0}%
\renewcommand\insertsectionnumber{\Alph{section}}%
\only#1{\part{\appendixname}
\addtocontents{nav}{\protect\headcommand{\protect\beamer@appendixpages{\the\c@page}}}}}
\makeatother
\begin{document}
\section{test1}
\begin{frame}{\insertsectionnumber.~\insertsection}
bal bla
\end{frame}
\appendix
\section{test2}
\begin{frame}{\insertsectionnumber.~\insertsection}
bla bla
\end{frame}
\end{document}

I would suggest that this is a bug in
beamerbecause it does not follow the usual interface thathyperrefhooks into. The following patch allows thebookmarksnumberedoption to have an effect:Result
