# Highlighting a page in an index

I would like to highlight one entry in an index.

If I have an index that appears several times in a document I would like to highlight one of these entries as the main one.

Something like

My Entry, 2, 4-5, 10, 15

Where page 10 is the main one.

Is there an easy way?

Edit

I am using imakeidx with several indexes. Something like this

\documentclass[a4paper,10pt,twoside,twocolumn,openany,justified,nomultitoc,bookmarksopen=true]{dndbook}

% nomultitoc is needed if the list of figures is not displayed
% the multitoc package need the lof,lot,loc options (and from version to version it seems not to work)
\usepackage[toc,lot,lof]{multitoc}

\usepackage[]{imakeidx}

\makeindex[name=Persone,title=Persone e mostri,intoc]
\makeindex[name=Luoghi,title=Luoghi,intoc]
\makeindex[name=Oggetti,title=Oggetti,intoc]

\indexsetup{noclearpage}

\begin{document}

Bla bla\index[Persone]{My Entry} bla bla

% [...]

Bla bla\index[Persone]{My Entry} bla bla

% to correct the PDF links
\phantomsection
\printindex[Persone]

% to correct the PDF links
\phantomsection
\printindex[Oggetti]

% to correct the PDF links
\phantomsection
\printindex[Luoghi]

\end{document}


But I am open to other options

• @RüdigerVoigt Actually the linked answer is about ordering the bold entries first. – Matteo Dec 3 '19 at 18:48
• @Matteo:... which includes code how to highlight an entry. However, I have to admit that the answer by Peter Wilson is cleaner / better code. – Rüdiger Voigt Dec 3 '19 at 20:51

\index[Persone]{My Entry|textbf}


will print the page number in the index in bold, whereas on other pages

\index[Persone]{My Entry}


will print a normal page number.

• I tried but it just prints My Entry, 10,textbf20,20 if the entry at page 20 is marked with \index[Persone]{My Entry|\textbf} – Matteo Dec 3 '19 at 18:51
• In your answer I see |\textbf with the unnecessary . If I try to edit it, the  is not there. – Matteo Dec 3 '19 at 19:08
• @Matteo Sorry, my typo, which I have corrected. It should have been just textbf not \textbf. – Peter Wilson Dec 3 '19 at 19:09
• OK I tried to edit it, but my browser showed a cached version :-) – Matteo Dec 3 '19 at 19:10
