Set up and Positioning
If you don't currently use an adjustable keyboard/mouse tray, consider attaching one to your surface.
Make sure the height of your keyboard allows you to keep an "open angle" with your arms.
If your keyboard is lower than the desk surface, tilt the back edge of the keyboard slightly down (known as "negative keyboard tilt").
If you use a keyboard tray, make sure there's enough room for your mouse.
If you have a broad chest, consider a "split" keyboard.
Tips for Healthy Keyboard Usage
Use a light touch when typing (don't bang on the keyboard!) .
Keep your wrists in a neutral (straight) position—not bent up or down.
Keep sure your elbows at a slightly open angle—90I or greater.
Keep your shoulders relaxed, and your elbows at your side.
Don't use wrist rests or armrests while typing—only while resting.
Stay centered on the lettered part of the keyboard.
Consider using a voice recognition software program.
Consider using keyboard shortcuts or macros to repeat common tasks.
