How to break line in #3 of \pdfcomment

Question

My question is as the title suggests.

\documentclass{article}
\usepackage{pdfcomment,xcolor}
\begin{document}
\pdfmarkupcomment[markup=Underline,color=blue!1,timezone=+08’00’]
           {Department}
           {name\\ Tel：123456}
\end{document}

Answer 1

hyperref defines \textCR for this:

\documentclass{article}
\usepackage{pdfcomment,xcolor}
\begin{document}
\pdfmarkupcomment[markup=Underline,color=blue!1,timezone=+08’00’]
           {Department}
           {name\textCR Tel：123456}
\end{document}
