Are you aware of Sioyek[0]? It's a PDF viewer with a fairly minimal UI and a focus on keyboard interaction.

SumatraPDF: https://www.sumatrapdfreader.org/free-pdf-reader

No frills, super fast and small. Been using it on Windows for years.

I recently downloaded SumatraPDF to open a PDF on Windows XP. Glad they still host a release that works on it. :)

Need wine (or something stronger) to run it on Linux.

Thanks, I love finding little nuggets like this here.

Eh, it vendors an old version of mupdf. Very bad idea, considering that it's a C program/library handling a notoriously complex format often shared on the Internet.

Personally, I just use mupdf (which I sandbox through bubblewrap).
