> Relaxed Grip: Maintain a relaxed grip. Tension in your hand and arm will make it harder to control the key and can introduce unwanted movements.

> In essence, the "handling" of the semi- automatic key bug to avoid unwanted "wrist rotation" artifacts is to adopt a proper operating technique that emphasizes forearm support and a smooth, side-to-side rolling motion of the wrist, minimizing forceful finger action and vertical hand movement. With practice and conscious attention to your hand and arm movements, you can develop a clean and efficient sending style on a bug.
