Abstract: A method of typing to reduce repetitive strain injuries comprises coordinating the movement of all moving parts from the shoulders to the fingers to avoid dissonant movement of any one part, starting with the hand and forearm in a natural profile. Each separately moving part is limited to movement to within its mid-range of motion. For speed, a finger is lifted and the hand is rotated to amplify the elevation. Conversely, lowering of the finger to strike a key involves rotating the hand in a reverse direction. The fingers are simply dropped, aiming at the top of the key to eliminate wasteful downward force and reduce finger-to-keyboard impact. Major movement of the fingers about the keyboard occurs simultaneously with upper and lower arm motion to eliminate stressful finger motions. A mouse manipulation method also employ the hand in a natural profile.
