Check out Lenovo's helpful page on the Pause key on keyboards, which features almost no real facts that I can discern!
No, however, depending on a device’s layout certain operations could potentially gain advantage from using ‘Pause’ functionality… e.g.: Smart phone menus where ‘Back and Home’ icons have been removed entirely. Also take into account that certain keyboards themselves may end up not having mentioned combination either thus prohibiting usage whole together.
