Hmmmm...  Then I guess I'll reconsider.  I can think of a way to keep the
key from walking on the balance rail pin, but it would be rather invasive --
not worth it for a retrofit.  The idea would be stolen from a children's toy
I'm at a loss to name or describe.  Ummmm....  One of those floppy,
cascading thingamagigs...  You know... With the wood blocks and the cloth
straps...  <hurumph...>  Anyway, I think I'll leave it alone.

Thanks, Isaac.

Peace,
Sarah
