Text Formatting ⇒ footmisc, footnotebackref, hyperref | Footnotes in Equations

[svend_tveskaeg]

Hi all.

Consider the following MWE:

Code: Select all

\documentclass[danish]{article}

\usepackage{babel}
\usepackage{mathtools}
\usepackage{footnotebackref}
\usepackage[bottom,hang,stable,symbol]{footmisc}
\usepackage{hyperref}

\begin{document}

We have\footnotetext[2]{See \nameref{addendum}.}
\begin{equation}
  a \stackrel{\mathclap{\footnotemark[2]}}{=} b.
\end{equation}
Furthermore
\begin{equation}
  c \stackrel{\mathclap{\footnotemark[2]}}{=} d.
\end{equation}

\section*{Addendum}
\label{addendum}
Something.

\end{document}

I would like the two \dag symbols in the equations to link interactively to the footnote.

How do I do this?

Thank you in advance!

Hi,

are you really sure it's worth the effort? Do you expect users to click there?

hyperref doesn't support \footnotemark with optional argument, due to technical issues. You could make a workaround without the optional argument. The hyperref README file shows ways and examples. Just use your PDF reader search feature and let it search for the word "nasty" - the only match is the solution.

It is for myself.

I have found the example (on pages 27--28), but I cannot get mine to work when I tried to modify my example in the same way.

Any chance that I can get you to modify my MWE in order to make it work? (I do not mind it being a number instead of a \dag.)

Thank you in advance!

I will have a look, perhaps not today, as I'm currently travelling, but tomorrow evening may be possible.

Thank you very much!

P.S. Have a nice trip.

The combination of a nasty workaround with hyperref to use an unsupported footnote feature, together with the footmisc package and footnote backreferencing, that's a bit too much, I guess. For example it's unclear where a back reference should point to, if there are several references.

I did not test the second suggestion from the hyperref README, just the first one. It works with hyperlinks to the daggers, if footnotebackref is not loaded:

Code: Select all

\documentclass[danish]{article}

\usepackage{babel}
\usepackage{mathtools}
%\usepackage{footnotebackref}
\usepackage[bottom,hang,stable,symbol]{footmisc}
\usepackage{hyperref}

\begin{document}
\stepcounter{footnote}% to start with the dagger
We have\footnote{See \nameref{addendum}.}
\addtocounter{footnote}{-3}%
\addtocounter{Hfootnote}{-3}%
\begin{equation}
  a \stackrel{\mathclap{\footnotemark}}{=} b.
\end{equation}
Furthermore
\addtocounter{footnote}{-4}%
\addtocounter{Hfootnote}{-4}%
\begin{equation}
  c \stackrel{\mathclap{\footnotemark}}{=} d.
\end{equation}

\section*{Addendum}
\label{addendum}
Something.

\end{document}

With footnotebackref, the hyperlinks get lost.

Spot on!

Thank you very much.
