Expected Behavior

Caller should be able to hook into left/right arrow key events and be have access to which list item was active when the arrow key was pressed. This would be beneficial to allow for behaviors such as left/right arrow keys to traverse through a nested list (such as traversing a multi-level file browser or a tree).

Actual Behavior

Unable to know which item is active when right/left arrow is pressed. Also, there is no way to listen for the left/right arrow key without wrapping the List in a Keyboard component.
