These new flyouts will appear when you press the volume or brightness keys on your laptop
This is the part I missed. It's only on Laptops.
If I press the Volume FN key it brings up the
new volume slider in the image.
Hi CK,
This is on a desktop Dell XPS 8930.
Apparently, it is not just for laptops. In this case it is just for the volume, there is no FN key for the brightness on this keyboard.
