Natural Ergonomic Keyboard 4000 requires some software for work. It comes in a bundle on a CD. The software is to be installed before connecting the keyboard to the desktop. The keyboard requires a free USB port to connect and won’t work with a PS/2 adapter. Obviously, because a lot of programmable buttons ask for a data exchange channel.
Natural Ergonomic Keyboard 4000 features five Favorites buttons and a batch of programmable ones. The silver-colored programmable buttons take the top edge of the Microsoft Natural Ergonomic Keyboard 4000. They can be preprogrammed to open a browser window, an e-mail client, control media playback, and open the desktop calculator. The default programs can be changed to a user’s liking, i. e. IE can be swapped for Firefox or Google Chrome and Outlook – for Hotmail. The key can be programmed also to bring up an entirely different application, or open a particular file. The five Favorites buttons has unchangeable functions assigned to them. My Favorites button calls up a window that shows the list of the functions in question.

The function keys on Natural Ergonomic Keyboard 4000 also sport additional features. There’s a special F lock to toggle between them. With the F Lock on, which is the default position from the box, they perform their standard functions. With the F Lock off, they execute a number of shortcuts, including undo/redo, save, print, and reply/forward/send for e-mail programs. The F keys are all labeled with their secondary functions.

And as a cherry on a top of a cake, Microsoft added two-arrows buttons just below the space bar. It’s meant for web pages’ navigation. The LED indicators are placed in a column just below these arrow buttons, installed in a metal strip that divides the wrist rest pad in half.

Natural Ergonomic Keyboard 4000 is a bulky keyboard and takes a lot of place. It doesn’t come in a set with a mouse. The convex shape is claimed to optimally fit the human hands and prevent the carpal syndrome. Yet, this shape takes time to get used to.

The wrist rest pad, though leatherette as such, is a bit harder than the gel pads.

The keyboard is said to be very silent except for the space bar which is said by many to have a clacking sound.

Wiki reports, Natural Ergonomic Keyboard 4000 is available in two variants, Business and Retail. Yet, no features of the Business edition are revealed.

  • Your comments are nice, but you left-off very important details. I just installed the Microsoft Natural Ergonomic 4000 Keyboard. System rebooted correctly and the keyboard worked. The keyboard did not have the software disc, nor did it come with a user manual or any instructions. How do you program the usable keys and get them and the F keys to function properly. Outside of the regular keyboard functions, the rest of the keyboard keys functionality are useless.

    • Hi.

      You have to install Microsoft Mouse and Keyboard Center to program the usable keys from within this software. You can download the app from the Microsoft official site.

  • Don’t worry about the ambiguous future, just work hard for the sake of clarity
