The Comfort Keyboard is infinitely adjustable. Move sections farther apart or closer together for your shoulder width. Start out straight and then gradually adjust until it is angled. Place the numeric keypad in the middle or on the left. Your body knows what it likes.
Remapping lets you to reassign virtual keys to different physical locations and this is great for software requiring repeated use of a key. If you type a series of characters repeatedly, you can program that into a macro key and give your fingers a rest. You can also program the left or right space bar to be the backspace key.
