How do I disable the fna shortcut?

When I press and release these, it makes the dock appear, highlights the TV icon in the dock, and defocusses the current window.

After I removed the TV.app icon from the dock, it now focusses the Finder icon.

How do I disable this entirely? I don't want fna to have any OS functionality.

I already tried System Preferences > Keyboard > Modifier Keys, set function to No Action, but that didn't change anything (and Press Globe to... is already "Do Nothing")

  • Sorry if this seems rather obvious, but why not just avoid pressing that shortcut key combo?

  • @Allan it's a common key combination in a game I play. For some reason I'd been able to play fine before years ago (mb fn+a is a recent macOS addition? I can't find out bout it online), but now I keep getting kicked out of the window and dying because the dock pops up out of nowhere

    Just a thought…it’s probably better to remap the shortcut in the game rathe than try to remap a system wide shortcut.

    +1 to negate the down vote. I’m not a gamer so it’s not applicable to me, but this is a valid question especially given that you disabled the Fn key.

As you mentioned that you are up for a third-party solution, I have successfully blocked macOS 13.x from responding to fn+a by using a tool called BetterTouchTool:

Keyboard shortcuts / press '+' on the bottom to add a trigger, press fn+a, select 'Click here & select action', select 'no action'.

configuration to macOS from responding to fn+A

Note: The application is not free and it might be overkill for just this use case if you can find a way to accomplish this with Karabiner. I'm not affiliated with the developer.
