Difference between IsMouseOver and IsHighlighted in WPF styles

Question

As in the title, I was wondering what is the difference between IsMouseOver and IsHighlighted property triggers in WPF styles.

Does anyone know?

Answer 1

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
