Hi, Bill,

As Katie mentioned before, each key can be pressed on the four sides.

It seems each key is being kept in place by some sort of mechanical spring component.
I can feel the spring action when pressing the key, but there is no mechanical feedback of a key being pressed (this is not a good classic HP keyboard after all).

In fact, I realize now that some of the key contacts are not registering on the first key press, so I really feel the pressure to dismantle it piece by piece just to see how did they engineered it and try to repair it.
But not right now. I have to wait for a better moment when I have the time and the right mood to start and finish this hobby task!
