I have… a lot of feelings towards Neovim, but putting those aside for the time being, it’s still my preferred LaTeX editor on my Mac.
What my LaTeX editing setup was missing1, though, was the ability to “jump to” a location in the output PDF from the code, or to jump to a location in the code by clicking on the PDF.
That capability is provided by SyncTeX, which causes the typesetting process to output a doc.synctex.gz
file2 which, when read by a compatible editor/PDF viewer, contains location information to enable the jumping.
