[GreenKeys] ASR 32/33 "Key Buffing"

[Paul Birkel]

Said john at johnwhitney.com:  "Now I notice my Q key looks a little tatty.
Will need to pull that out and buff it up a little."

I'd appreciate guidance for "tattiness removal" :->.  What is the collective
wisdom on this point, and why do ASR 33/22 keyboards get this way?

Thank you,

paul
