IsHighlighted
takes any input device (like keyboard) into consideration for showing logical focus. It is not a DependencyObject
level dependency property, as far as I researched it is available only for following 3 controls in WPF:
System.Windows.Controls.ComboBoxItem.IsHighlighted
System.Windows.Controls.MenuItem.IsHighlighted
System.Windows.Controls.Primitives.CalendarDayButton.IsHighlighted
