How to bind a function to the Windows key

Question

I want to bind the function evil-normal-state to the windows key on my keyboard. How do I do that? Also is there a way to bind the Fn key to other functions?

I am using Emacs 26.1 on a Linux-Mint system.

Answer 1

On my system, the Windows key is intercepted by the desktop manager, so Emacs doesn't see it. As for the Fn key, C-h c says that Emacs sees this key as <XF86WakeUp>; so, for example, I could bind it to execute-extended-command with:

(global-set-key (kbd "<XF86WakeUp>") 'execute-extended-command)
