Beamer: Navigation bar jumping to last slide of first frame

Question

I am using the Frankfurt-theme in beamer. When I use the navigation bar the presentation "jumps" to the first slide of that section (showing only "A" in the presentation, see mwe). However, usually I am using the navigation bar after a presentation. Therefore, it would be preferable that the presentation jumps to the last slide of the first frame (e.g. showing "AB" in the presentation, see mwe). Is there a way to achieve that effect? And how?

\documentclass[xcolor=dvipsnames,onlyslideswithnotes,t]{beamer}
\setbeamertemplate{footline}[frame number]
\usetheme{Frankfurt} 

\setbeamertemplate{navigation symbols}{}

\begin{document}
\section{Jump}
\begin{frame}
A \pause
B 
\end{frame}

\begin{frame}
CD
\end{frame}

\section{Hide}
\begin{frame}
EF
\end{frame}

\end{document}

(Note: The question Beamer: how to navigate to the last slide of next frame seems to be related to my question.)

Answer 1

This behavior is controlled by (beamerbasenavigation.sty line 734-741)

\def\beamer@link(#1/#2){%
  \def\beamer@goto{{Navigation#1}}% default: first slide of frame
  \ifnum\c@page<#2%
  \ifnum\c@page<#1\else% go to last slide of frame, on all slides of
                                % the frame, except for the last one
  \def\beamer@goto{{Navigation#2}}% jump to last slide of frame
  \fi\fi%
  \expandafter\hyperlink\beamer@goto}

Here is the logic in human language: Say there is a frame that spans across pages 5, 6, 7, 8 and you click the hyperlink dot.

• At page 1-4, you will be brought to page 5.
• At page 5-7, you will be brought to page 8.
• At page 8-end, you will be brought to page 5.

You can redefine this macro to achieve your logic, for instance

\def\beamer@link(#1/#2){%
    \ifnum\c@page<#1%
        \def\beamer@goto{{Navigation#1}}%
    \else%
        \def\beamer@goto{{Navigation#2}}%
    \fi%
    \expandafter\hyperlink\beamer@goto%
}

• At page 1-4, you will be brought to page 5.
• At page 5-end, you will be brought to page 8.

One more example

\makeatletter
\def\beamer@link(#1/#2){%
    \ifnum\c@page<#1%
        \def\beamer@goto{{Navigation#1}}%
    \else\ifnum\c@page<#2
        \def\beamer@goto{{Navigation\the\numexpr\c@page+1}}%
    \else\ifnum\c@page=#2%
        \def\beamer@goto{{Navigation#1}}%
    \else%
        \def\beamer@goto{{Navigation#2}}%
    \fi\fi\fi%
    \expandafter\hyperlink\beamer@goto%
}

• At page 1-4, you will be brought to page 5.
• At page 5-7, you will be brought to the next page.
• At page 8, you will be brought to page 5.
• at page 9-end, you will be brought to page 8.

This one allows you to cycle through the frame by smashing the hyperlink dot.
