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.
