💡 Proposal - useKeyboard hook in f36-utils

The problem

I see in our code base we have many approaches devs takes to listen to keyboard events and detect keycode, …etc.

const handleKeyUp = (e: React.KeyboardEvent) => {
    if (KeyCodes.esc(e)) {
      hidePanel();
    }
 };
document.addEventListener('keyup', (handleKeyUp as unknown) as EventListener);
return () => document.removeEventListener('keyup', (handleKeyUp as unknown) as EventListener);

That I believe we can make simpler, and since it’s considered as interactions, I believe it would fit well in F36

The proposed solution

A simple hook that accepts a reference or a document, adds/remove the events on mount and unmount, and finally emits callback functions

Also maybe some predefined ones for what we think is the most keyboard buttons we need to listen to?

const { onEsc, onEnter, onKey } = useKeyboard(ref | document);

onEsc(() => alert('👹'))

onKey('h', () => alert('hello'))
