React RadioGroup - Keyboard Support

An end user can use the following keys to interact with the UI component.

Key Action
↑ or Page Up Moves focus to the previous radio button.
↓ or Page Down Moves focus to the next radio button.
Home / End Moves focus to the first/last radio button.
Enter or Space Selects the focused radio button.

You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
