[Elecraft] Off-Topic - Straight-key speed cpontrol

That's very similar to what I had in mind.

Here is a link to my sketch, kindly hosted by David G4DMP

In my style, the pressure comes from the middle finger onto the disc and 
that finger takes all of the bounce.  I find bunching the fingers together 
onto the key knob very tiring and I've added a disc to several keys.  I have 
thousands of these discs, so, if anyone wants some, let me know.
