# back-hyperref the whole word

I use the following codes

\documentclass[12pt,a4paper]{article}
%------------------------------------------------------------
\usepackage{amsmath,amssymb,amsthm}
%------------------------------------------------------------
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{xcolor}

\newtheorem{corollary}{Corollary}[section]
\newtheorem{proposition}{Proposition}[section]
\newtheorem{lemma}{Lemma}[section]
\newtheorem{remark}{Remark}[section]
\newtheorem{example}{Example}[section]
\numberwithin{equation}{section}

\begin{document}
\begin{corollary}\label{cor}(\cite[Corollary 3]{4})
A unilateral weighted shift $T$ on ....
\end{corollary}

By Corollary \ref{cor}, there exists a polynomial......

\begin{thebibliography}{10}

\bibitem{4}{W. Arendt, J.R. Goldstein, and J.A. Goldstein:} {Outgrowths

\end{thebibliography}

\end{document}


I get

When I clic on the number 0.1, I go back to corollary 0.1. However, I hope that when I clic also on the word Corollary I go back to corollary 0.1. Like in the following paper:

You can use the cleveref package to

• automatically insert the word "Corollary"

• make the complete name click-able

\begin{corollary}\label{cor}

\end{corollary}

By \cref{cor}, there exists a polynomial......

• Thanks a lot for your answer. For references, how can I do? I try with \cref[Corollary 3]{4} but it is not correct. I hope to insert also Corollary 3 like in the picture. – Student Jan 14 '19 at 12:40
• @Student If you have the source code of the referenced paper (can be downloaded e.g. from preprint platforms such as arxiv) you can use the same technique in combination with the xr-hyper package. Other solutions with bibliography tools such as biblatex are also possible. – user36296 Jan 14 '19 at 12:45
• I hope that you include my example in your answer. Thank you very much. – Student Jan 14 '19 at 12:48
• Please see the picture. Perhaps you don't understand me very well. I want to cite a reference like \cite[Corollary 3]{4}. I hope that when I clic on the word Corollary 3, I go back to bibliography. However with my codes, I must only clic on the number 1 which is in red color. Thank you in advance for your help. – Student Jan 14 '19 at 13:13
• @Student In the text of your question, you ask how to add the link to corollary 0.1 - this is what I answered. If you insist on doing your bibliography be hand, see tex.stackexchange.com/questions/285710/…, otherwise a bibliography tool like biblatex could help – user36296 Jan 14 '19 at 13:20
