FYI Framework logo on F12 is XF86AudioMedia

I use arch with i3wm. In the config file you have/can specify keyboard shortcuts. The keymap for the framework logo on F12 is “XF86AudioMedia”.

So you can use that to map your keybindings. Like:
bindsym XF86AudioMedia exec --no-startup-id ‘command’

That it would be helpful since it is a unused in most distros.

You can see more key symbols from F1 to F12 here on ArchWiki . And here is the i3 or sway config file including the Fn keys bindings.
