Help for \HyperRaiseLinkHook needed

[Uwe-Schmock]

So far I was able to raise the hook of internal links for better hover preview as offered by TeXShop, for example.
For unknown reasons, this doesn't seem to work anymore.
I seem to be using hyperref 2026-04-24 v7.01q.
Here is a small example file:

\documentclass{article}
\usepackage{amsmath}
\usepackage{hyperref}

\makeatletter
\newcommand{\RaiseHook}[1]{\renewcommand\HyperRaiseLinkHook%
{\setlength\HyperRaiseLinkLength{#1\baselineskip}%
\global\let\HyperRaiseLinkHook\@empty}\ignorespaces}
\makeatother

\begin{document}
\noindent
Vandermonde's determinant:
\RaiseHook{3.2}  %Supposed to make the matrix fully visible when clicking on the link below
\begin{equation}\label{VandemondeDet}
\det\begin{pmatrix}
1&x_1&x_1^2&\ldots&x_1^{d-1}\\
1&x_2&x_2^2&\ldots&x_2^{d-1}\\
1&x_3&x_3^2&\ldots&x_3^{d-1}\\[-1\jot]
\vdots&\vdots&\vdots&\ddots&\vdots\\
1&x_d&x_d^2&\ldots&x_d^{d-1}\\
\end{pmatrix}
\end{equation}
To calculate the determinant (\ref{VandemondeDet}), we proceed by induction $\ldots$
\end{document}

Any suggestions how to get back the old behaviour?
Thanks a lot in advance!

Your code should work again, if you add this:

\makeatletter

\newlength\HyperRaiseLinkLength
\renewcommand\HyperRaiseLinkDefault{\normalbaselineskip}

\AddToHook{makelinktarget}
  {\setlength\HyperRaiseLinkLength{\HyperRaiseLinkDefault}%
   \HyperRaiseLinkHook
   \setlength{\normalbaselineskip}{\HyperRaiseLinkLength}}

\newcommand{\RaiseHook}[1]
 {\renewcommand\HyperRaiseLinkHook%
 {\setlength\HyperRaiseLinkLength{#1\normalbaselineskip}%%normalbaselineskip is imho better
  \global\let\HyperRaiseLinkHook\@empty}\ignorespaces}

\makeatother

I should probably add this directly to hyperref to support the old hooks.

A more direct method to raise the next anchor would be

\AddToHookNext{makelinktarget}{\setlength{\normalbaselineskip}{10cm}}

[Uwe-Schmock]

Thanks a lot, works great and saves all the work I put into placing these hooks!
Actually, I now redefined \RaiseHook as follows:

\newcommand{\RaiseHook}[1]{\AddToHookNext{makelinktarget}%
{\setlength{\normalbaselineskip}{#1\baselineskip}}}

So far, this also seems to work fine.

As I wrote, I would prefer \setlength{\normalbaselineskip}{#1\normalbaselineskip}, \baselineskip can be zero in various places.
