Upcoming \footref macro in LaTeX kernel

[Arash Esbati]

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
