I am using the easiest way of tooltip code that posted in this answer by @AlexG. it works very well but in long tooltips, it doesn't break the lines in output (as shown in the following screen shot)
Q1: How can I use this
tooltipwith fixed width?Q2: How can I change the shape of this
tooltipbox? e.g. a hurt shape or circle instead of rectangle. (at least rounded corner rectangle.)
\parbox of given width: \tooltip****{foo}{\parbox{0.8\linewidth}{... long text ...}}
\fcolorbox in the tooltip code with, e. g., \tcbox from package tcolorbox %\fcolorbox{black}{#7}{#8}%
\tcbox[colframe=black,colback=#7,size=fbox,arc=1ex]{#8}%

\tooltip{my Theorem}{\ref{thm:2}}?

\tooltip command with 2 and more *). This is due to a limitation of the PDF file format. But you can disable hyperlinks inside the box: \tooltip{my Theorem}{\begin{NoHyper}\ref{thm:2}\end{NoHyper}}

\tooltip{my Theorem}{\begin{NoHyper}\ref{thm:2}\end{NoHyper}} not working. I think it needs something like \expandafter maybe.

\ref{} inside \begin{theorem} \end{theorem} .i.e. \tooltip****{Theorem}{\begin{theorem}\ref{thm:2} \end{theorem}}that the\tooltiphas some problem withtheorem` env.

\tooltipcode, replace\fcolorboxwith something fancier, maybe from packagetcolorbox. – AlexG Sep 26 '19 at 07:10
