* Keep the wrist in a neutral position: parallel to your desk and the middle finger must be in line with the wrist and forearm.
* Don't rest your wrist while typing, let it float. Only rest your wrist while you are NOT typing.
* Use a light touch when pressing keys.
* Don't stretch your fingers to reach for faraway keys. Instead move your arm to position your finger over the key and then hit it.
* Do not hold your thumbs rigid or your pinkies up. Curve your fingers.
* Don't use two fingers of one hand for two-key combinations. Use one finger of one hand to hold Shift, Ctrl, or Alt down, and then hit the second key with a finger from the other hand.
What do you think. Do you follow those techniques? Any other suggestions?
