Select the proper ergonomic keyboarding techniques. keep your shoulders, arms, hands and fingers relaxed. your arms should be comfortable at your side, forming a 45° angle with your upper arms, and your forearms should be parallel to the floor. adjust the keyboard height so that your shoulders can relax and your arms are straight in front of you. position the keyboard directly in front and close to you so you don't have an excessive reach. position your wrists straight or in neutral position while typing. do not rest your hand on the mouse when resting. rest your hands in your lap when not working. push firmly on the keys and hold them down for long periods. if you are working for a long period of time, alternate between sitting and standing. take breaks to stretch. adjust your chair height and position so your feet rest flat on the floor, or add a footrest to compensate for a higher chair.

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. this is the way of typing :)
