React List - Keyboard Support

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

Key Action
↑ / ↓ Moves focus to the previous/next item.
Page Up / Page Down Moves focus to the item located a screen above/below the current one.
Home / End Moves focus to the first/last item.
Enter or Space Selects the focused item.
Shift + ↑ / ↓ Shifts the focused item one item up/down. Active if the allowItemReordering property is set to true.
Delete Removes the focused item. Active if the allowItemDeleting property is set to true.

Use the registerKeyHandler(key, handler) method to implement a custom handler for a key.
