A straight Morse key has a fulcrum away from you, but your wrist
articulates in front of the key, in a mirror image of that of the key.
Therefore, your wrist is constrained to follow an unnatural arc
when keying.
Have there been any mechanical designs published so that the
keying arc is in the same sense as the wrist arc?
(cf. Watts' parallel motion, perhaps?)-

How about keeping the key turned 180° (facing away from you)?!

That thought did occur to me in bed last night. The main difficulty
would be
in needing a special-purpose table with an indentation...............by
having a
downward right angle bend for the paddles, you keyed
horizontally.


Hi OM Gareth.

Or the key should be below the table-top with only the knob projecting
out!


Yes, the knob protrudes, but the skirt of the knob is flush.
