The Microsoft standard typing and key control ergonomics are typical of IBM 104-key enhanced layouts. Heavier touches are generally reserved for less experienced or occasional typists. Immediately beyond that point, the force is sharply changed so that users can easily "feel" when the key has been pressed sufficiently. Optimum force/displacement characteristics of a key require a steadily increasing force as the key is depressed until contact is made. Also, excessive force induces finger fatigue. If too little force is required, extra keys may be struck accidentally, and if too much force or displacement is required, some keys may fail to be actuated because the user did not press hard enough. The more proficient the user, the lighter the touch can be. Key forces for current high production (read: good quality) keyboards are in the range of 40-125 grams with key displacements of 3 to 5 mm. Efficient keying requires that keys function with minimum adequate force and with sufficient displacement to provide muscular feedback to the user. The Goldtouch KOF is rated at 54 grams, and the Unotron KOF is 65 grams. By comparison, the Kinesis Maxim keyboard with its smooth operating high quality mechanical key switches has a KOF of 51.7 grams. The average maximum key operating force (KOF) is a moderate 55.5 grams making the touch very familiar, and similar to other good quality membrane-based keyboards. Key contact bounce for the Microsoft Natural Ergonomic Keyboard 4000 is good at 10 milliseconds. A series of indicator (LED) lights are positioned vertically between the halves of the palm/wrist rest. The front edge of the keyboard is covered with a very nice, heavy gauge, matte, textured vinyl palm/wrist rest which works well for a good range of hand sizes.

The keyboard is supplied with an installation CD which updates the keyboard Control Panel applet, providing control and customization for 30 different keys-all 22 additional keys, plus the Caps Lock, Left Windows and Application keys. Most of the multimedia and application keys are programmable. In addition, the standard IBM 104 Enhanced Key layout is augmented by 22 multimedia and application keys for control of various programs including Word, Excel, Outlook, Media Player, Internet Explorer and basic audio.

While you may be familiar with Microsoft's Natural Keyboard Elite Pro which has been around for almost seven years, the Natural Ergonomic 4000 adds a curved keywell to the split, tented design. The Microsoft Natural Ergonomic Keyboard 4000 is a small but interesting step forward for Microsoft.
