Jakube I see that some of the F keys don't work with new Spell Book (e.g. F23 works, F24 doesn't).
This happens because these keys could be occupied already by Windows itself. Current system I use, doesn't allow me to register occupied shortcuts (in Excalibur system is different).
At some point I might explore a workaround for this.
If you use StreamDeck I would just use URL link from Spell Book.
