Subject: bug#58425: Unable to achieve advertised "word-level" accuracy using SyncTeX with PDF Tools

[Message part 1 (text/plain, inline)]

From the AucTeX Changelog (v. 11.89):

"To open the PDF output file you can now also use PDF Tools, a document
viewer for Emacs. With it, as a plus, forward and backward search is
accurate at word level."

I'm only able to achieve word-level accuracy on reverse sync search. On
forward sync search, the arrow that appears in the left-hand margin of the
PDF preview buffer can be off by as much as a half-dozen lines.

Is there a way to configure AucTeX+PDFTools in order to highlight the word
in the PDF Tools preview buffer corresponding to where the cursor is
positioned in the AucTeX latex source buffer during a forward search
instead of placing an arrow in the left-hand margin, which by construction
can only be line-level accurate at best?

Emacs 28.2 (MSYS2) w/ latest pdf-tools.
