Yes, sorry, that should have been SDLK_SCROLLOCK instead - I pushed a
patch already.

No.

Yes. It's normally the key between PRINT and PAUSE. Looking at
https://upload.wikimedia.org/wikipedia/commons/e/e9/Clavier_ergonomique.JPG
the key is called "Arret defil" in french?

Unfortunately, it is not available on modern laptop keyboards anymore
(but I still have it on my external keyboard). But there's normally a
magic shortcut to trigger this key on laptop keyboards, e.g. on my
Lenovo T440, I have to push Fn + k to get a SCROLL LOCK key press.
Just try to google for you laptop type together with the keyword "SCROLL
LOCK" - I hope there will be one for your laptop, too.
