[GreenKeys] Model 15 keycap removal

[drlegendre .]

You may well be correct, about the direction being CW.

When my M15 arrived, it had a couple of loose caps, and a couple more that
were simply crooked. The crooked ones were all off slightly CCW and I found
that turning them CW felt right - and they seemed to snug down. Likewise
the loose caps, they were about 1/4 turn CCW and it was easy to push down
and turn CW to secure them.

I came away from it with the sense that CCW was the way it should be done,
but that's only based on this one machine. Fwiw, all of the caps seem to
stay put just fine. Next time I work with it, I will definitely pay closer
attention to how the mating features are stamped.
