Function Key Pro is a macOS utility that helps you distinguish special function keys (e.g. volume up) and standard ones (F1, F2, etc.) WITHOUT Fn, and LAUNCH apps or complex multi-key hotkeys with a single press.
Great idea to be able to use long-press, and have the Function keys do almost whatever you want.
A few rough edges in the user interface such as it’s easy to accidentally lose an initial setup if you click the wrong button, it doesn't offer to save first.
