<!-- keyboard navigation -->
<!-- Here's how keyboard navigation works in radio groups on Windows:
The group takes 'focus'
The user is then free to navigate around inside the group
using the arrow keys. Accessing previous or following radio buttons
is done solely through the arrow keys and not the tab button. Tab
takes you to the next widget in the tab order -->

<!-- set a focused attribute on the selected item when the group
receives focus so that we can style it as if it were focused even though
it is not (Windows platform behaviour is for the group to receive focus,
not the item -->
