Problem: Currently unable to navigate the Search Engine settings
menu via (Bluetooth) keyboard navigation (up/down/tab/enter keys).
This is because the ListItems in the ListView (contains search
engine choices) are not focusable.

Solution: Make Search Engine settings options focusable, so that
they can navigated and receive click events with a keyboard
(up/down/tab/enter keys).
