Query: Keys click but nothing happens

Imagine pressing a key (like Enter or the decimal) you feel it click, you hear it click but nothing happens! OK maybe it was just a fluke, maybe I just thought I felt and heard a click - this time look at my finger as it carefully presses the Enter key: Yes I heard it this time, Yes I felt it this time, No nothing happened this time! Oh, if you press it just right it works but just because you hear & feel a click don't think it actually made contact. Recommendation: Forget it.
