[GreenKeys] Model 28 Unshift on space.

[Joe Duszyński]

Thanks all for the reply,
I took the box apart that was acting up......
It ended up being a hardened blob of "what probably once was grease" in the
area where the function lever goes into the pawl.
It was solid and hard as a rock and it prevented the lever from dropping.
I literally carved it out of that recess with an exacto knife and some
acetone.
