Dear all,
next LaTeX release will have a \footref macro built-in[1]
\subsection{Producing several footnote marks to one footnote}
It is sometimes necessary to reference the same footnote several
times, i.e., produce several footnote marks with the same number or
symbol. This is now always possible by placing a \cs{label} into the
\cs{footnote} and reference it with the command \cs{footref}
elsewhere. This way marks refering to footnotes anywhere on the page
(including those in \texttt{minipage}s) can be generated. In the past
this command was only available with certain classes or when loading
the \pkg{footmisc} package.

Adding support within AUCTeX is easy. Within RefTeX, we have to tweak
`reftex-ref-style-alist' which is defined like this:
(defcustom reftex-ref-style-alist
'(("Default" t
(("\\ref" ?\C-m) ("\\Ref" ?R) ("\\pageref" ?p)))
("Varioref" "varioref"
(("\\vref" ?v) ("\\Vref" ?V) ("\\vpageref" ?g)))
("Fancyref" "fancyref"
(("\\fref" ?f) ("\\Fref" ?F)))
("Hyperref" "hyperref"
(("\\autoref" ?a) ("\\autopageref" ?u)))
("Cleveref" "cleveref"
(("\\cref" ?c) ("\\Cref" ?C) ("\\cpageref" ?d) ("\\Cpageref" ?D)))
("AMSmath" "amsmath"
(("\\eqref" ?e))))
I suggest to change the "Default" entry like this:
(("\\ref" ?\C-m) ("\\Ref" ?R) ("\\pageref" ?p) ("\\footref" ?t)))
i.e., add \footref and bind it to t key. Any comment about tke key
binding?
Best, Arash
