Menus and Accessibility

For one of my projects, several testers asked for keyboard controls in my menus. Which, fair, I'd been using a mouse to test but I can see where keyboard would be easiest. This is the easiest video that I've ever found on using keyboard controls to navigate menus in Godot, it's very no nonsense and works out of the box quickly: See why I love it? I've thought about expanding this tutorial out to make it more accessible. I'm not really sure where the line is between "I jacked this guy's tutorial" and "Wow my own original content," but we're all just nerds typing @export var junk at the end of the day. Here's what I think I'd add in terms of accessibility:

• Dots or icons so you can see what's selected
• Sounds, a cute lil beep when something comes into focus
• Showing how theme interacts with focus
• Rumble. Okay maybe not, but that would be kinda fun, wouldn't it?

I'm not sure, what would you like to see?
