Anybody who uses vim would understand the motivation immediately.
By "Fn", I am referring to the key on laptops that switches between F1, F2, etc. and volume up, volume down etc.
This would be on linux in wayland, particularly sway.
It should be possible. I checked wev, and my Fn key does generate "XF86WakeUp" key events all on its own, without having to press any other keys.
