Answer 1

Based on this answer which almost worked, but not quite.

Put a KeyDown event on your ListBox and use its ItemsCollection to select the next or previous element when you see a Right or Left keypress.

That moves the selection, but not the keyboard focus (dotted line), so you must also call MoveFocus on the element that has Keyboard focus.

private void ListBox_KeyDown( object sender, KeyEventArgs e )
{
    var list = sender as ListBox;
    switch( e.Key )
    {
        case Key.Right:
            if( !list.Items.MoveCurrentToNext() ) list.Items.MoveCurrentToLast();
            break;

        case Key.Left:
            if( !list.Items.MoveCurrentToPrevious() ) list.Items.MoveCurrentToFirst();
            break;
    }

    e.Handled = true;
    if( list.SelectedItem != null )
    {
        (Keyboard.FocusedElement as UIElement).MoveFocus( new TraversalRequest( FocusNavigationDirection.Next ) );
    }
}

Finally, make sure you have IsSynchronizedWithCurrentItem="True" on your ListBox.

This will give you the wrap-around behaviour that you want.
