What Key is System.Windows.Input.Key.Clear [closed]

Question

I just realized there is a clear key defined in System.Windows.Input.Key. But the online help just states that it is the ”clear key“. No further information is given.

Can anyone tell me, what this key is and what it does?

Answer 1

Its 5 on a numpad when NumLock is off, so at the center of the alternate arrows.
