Description

It'd be awesome if you were able to detect the status of Caps Lock. A typical use case would be a log in screen where the password is case sensitive and being able to present an alert to the user when it's active.

This link supposedly does this but not in a very pretty manor.

Research direction
The issue requests a feature to detect Caps Lock status, commonly used in login forms. The library jwerty could expose a method to check the state. Research the KeyboardEvent.getModifierState('CapsLock') method available in modern browsers. Look at the source code in jwerty.js to see how keyboard events are currently handled and where a new method could be added. Consider creating a simple utility function and updating the documentation and tests. The issue has no assignee or linked PR, so it is available for contribution.
