Either way, try sending CW in the cockpit of a fighter plane. In WWII 
fighters the cockpit was very small. You hold the stick with your right 
hand. The throttle is on the left side. All the armament controls are on the 
left console. The radio stuff was mostly on the right side.

The main part I remember was the COMMAND SET stuff being on the right.

The main use of the CW key was getting a DF STEAR. All you had to do was 
hold the key down long enough for the tower to get your heading.
