Windows 8.1 - Audible confirmation of Caps Lock etc

Newer computers running Windows 8 have flatter keyboards, making typos a little easier for people accustomed to standard depth keys. Some keyboards do not even have a Caps Lock light to warn that you accidentally turned-on Caps Lock.

As a solution, there is an accessibility setting to sound a quick beep when you press any of the Lock keys:


 Swipe-from-left to see the "Charms" bar,
  then Settings ("gear")
  -> Change PC Settings (at bottom-right corner, not an icon)

   The PC Settings screen appears:
    -> Ease of Access
    -> Keyboard
    -> Toggle Keys (On).
