Microsoft Natural Keyboard 4000 5QH-00001 Black Wired Ergonomic Keyboard

Ergonomic USB Keyboard for Business Users

The Microsoft Natural Keyboard 4000 model 5QH-00001 is a wired USB keyboard with an ergonomic split-key layout and integrated palm rest. It provides 104 standard keys in a black finish and connects directly to a PC or Mac via USB. The design targets office professionals and home users who type for long periods and prefer a fixed, sculpted shape.

Sustained Comfort with Fixed Wired Connection

Because the keyboard draws power and transmits data over a single USB cable, there is no battery to recharge or wireless signal to manage during extended sessions. The integrated palm rest remains in a constant position relative to the key wells, supporting the wrists without shifting. Customizable hot keys and a zoom slider keep frequent commands within reach so workflow stays consistent over hours of use.

Upgrade from Flat Keyboards Without Extra Hardware

This model replaces a traditional flat keyboard when the priority is a built-in palm rest and a curved key bed that follows hand anatomy. It adds dedicated media and shortcut keys that many basic keyboards omit. Buyers who need a compact form factor, wireless freedom or a separate numeric keypad will not find those features here.
