[GreenKeys] Model 15 keycap removal

[Bill Strangfeld]

I just experimented with removing some keycaps on an old model 15.  Results
were better by turning them a quarter-turn clockwise to remove than by
turning them counter-clockwise.  Turning them counter-clockwise consistently
made them loose when they were reinstalled.  

When I reinstalled the ones that I turned clockwise to remove, they were as
tight as before removal.

But when turned CCW to remove, there apparently is interference between the
two retaining indents on the bottom of the keycap and two small tabs on the
round part of the keyboard lever, where the keycap fits.  It looks like this
bends the keycap indents and makes the keycap fit loose and sloppy.  Those
indents might be bent back to tighten the fit but it is a delicate job.  It
is all too easy to tear the thin metal and ruin the keycap.

This was a small sample and your results may differ.

    Ah, thanks.  The keycaps were just stuck.  I've been able to replace
most of the missing keytops from spares.
