[Tex/LaTex] How to make indexed words clickable in the text

hyperrefimakeidxindexing

I want to make the indexed words into hyperlinks to the entries in the "Index" (something similar to the glossaries package).
I'm using xindy on TL2012 and here is my code:

\documentclass{article}

\usepackage{makeidx}
\makeindex

\usepackage{hyperref}

\begin{document}

Lorem\index{Alpha} ipsum dolor sit amet, consectetur\index{alpha}
adipiscing elit. Proin ullamcorper\index{gnat} quam magna, quis
convallis\index{gnus!good} sapien. Donecat ligula vel dolor
varius\index{bites!vegetable} lobortis id ut orci\index{gnat!size
of}. Maecenas commodo fringilla elit\index{Alphabet}, et pellentesque
purus ornare vitae.  Aenean non metus ipsum. Lorem\index{gnat!anatomy}
ipsum dolor sit amet, consectetur adipiscing\index{alphas} elit. Ut
mauris lorem, accumsan a sagittis ut, rutrum fringilla arcu. Cras
ullamcorper faucibus\index{alpha bet} quam id molestie.

\printindex

\end{document}

How can I do that?

Generally the indexed words do not necessarily appear in the text at all (for example there can be a fox in the text and an \index{animals} next to it). Therefore I'm not sure whether I understand your question right.

\documentclass{article}

\usepackage{makeidx}
\makeindex

\usepackage{hyperref}

\begin{document}

Lorem\index{Alpha@\hypertarget{Alpha.ind}{}Alpha}\href{\#Alpha.ind}{Alpha}
ipsum dolor sit amet, consectetur 
\index{alpha@\hypertarget{alpha.ind}{}alpha}\href{\#alpha.ind}{alpha}
adipiscing elit. Proin ullamcorper 
\index{gnat@\hypertarget{gnat.ind}{}gnat}\href{\#gnat.ind}{gnat} quam magna, quis
convallis
\index{gnus!good@\hypertarget{gnusgood.ind}{}good}\href{\#gnusgood.ind}{good} quam magna, ...

\printindex

\end{document}

Does this accomplish what you intended? (This works without xindy, but with it there can be problems.)

That is the default behavior as long as you load the hyperref package last:

enter image description here

\documentclass{article}
\usepackage{lipsum}
\usepackage{imakeidx}% For index generation
\usepackage{hyperref}% Load last (AFTER imakeidx)

\makeindex

\begin{document}
  \lipsum[1]
  \index{foo}
  \lipsum[2]
  \printindex
\end{document}

I'm just throwing this idea out there; not sure whether it might be of help. It is somewhat inspired by David's showkeys package:

enter image description here

\documentclass{article}
\makeindex
\makeatletter
\newcommand{\@theindexentry}[1]{%
  \smash{%
    \rlap{\rule{.4pt}{.8\baselineskip}}% Vertical rule
    \begin{lrbox}{\@tempboxa}\tiny\ttfamily#1\end{lrbox}% Box index entry
    \rlap{\raisebox{.6\baselineskip}{\usebox{\@tempboxa}}}% key
  }%
}
\def\@wrindex#1{%
  \protected@write\@indexfile{}%
    {\string\indexentry{#1}{\thepage}}%
  \endgroup
  \@esphack%
  \@theindexentry{#1}%
}
\def\@index#1{\endgroup\@esphack\@theindexentry{#1}}
\makeatother
\begin{document}
Lorem\index{Alpha} ipsum dolor sit amet, consectetur\index{alpha} adipiscing elit. 
Proin ullamcorper\index{gnat} quam magna, quis convallis\index{gnus!good} sapien. Donec 
at ligula vel dolor varius\index{bites!vegetable} lobortis id ut orci\index{gnat!size of}. Maecenas 
commodo fringilla elit\index{Alphabet}, et pellentesque purus ornare vitae. 
Aenean non metus ipsum. Lorem\index{gnat!anatomy} ipsum dolor sit amet, consectetur 
adipiscing\index{alphas} elit. Ut mauris lorem, accumsan a sagittis ut, 
rutrum fringilla arcu. Cras ullamcorper faucibus\index{alpha bet} quam id molestie.

Nunc et\index{alphabet} sem et turpis semper adipiscing et id nibh. In nibh 
mauris, placerat sed consequat placerat, dignissim ut\index{at!bat|see {bat, at}} arcu. 
Aenean eleifend justo volutpat lectus\index{gnus!bad} interdum pellentesque. 
Etiam cursus varius\index{twenty@xx} tellus, non pretium nibh tempus sit amet. 
Suspendisse sed mauris nisl. Cum sociis natoque penatibus et 
magnis dis parturient montes, nascetur\index{alpha@$\alpha$} ridiculus mus. Nullam 
at feugiat nisi\index{bites!animal!gnats}.
\end{document}

It prints, for every \index, a vertical rule showing the point of reference, as well as the key used (minus { or }, for simplicity) in \tiny\ttfamily. Using xcolor one could make the appearance less intrusive by printing in black!30 (say):

enter image description here

\@theindexentry prints the index-related content. \smash takes care of any vertical adjustment, while the entire index entry is set inside a zero-width \rlap to remove any horizontal adjustment.

The definition of \@wrindex (in the presence of \makeindex) and \@index was taken directly from latex.ltx.
