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?)

Setting aside the rather large flood of infantile pollution that some
have felt the need to inject into this thread (are they not
able to handle disagreement in an adult fashion?) the reason
for raising this subject and seeking details of prior experimentation
is that I have RSI in my wrist, caused by playing Freecell, and hovering
over the mouse for several minutes at a time whilst working out
my next move.

It seemed to me that by have a key that articulated on the same axis as the
wrist that the discomfort of manual keying of CW might be ameliorated.
