Removable Riser (attaches below the palm supports): Elevates the front edge of the keyboard to create "negative inclination".

Partially "Tented" Gull Wing Design: The keycaps transition from an approximately 14° angle on the innermost column down to 0° of tent on the outermost column of keys.

Preset Fixed "Splay": The keys are arranged with a limited preset degree of splay to help reduce ulnar deviation.

However care needs to be taken to ensure that other issues are not created (see Usage Tips for more detail regarding this). The "lift" accessory can address this even further by creating a "negative inclination" that actively directs the wrists towards a more neutral alignment. Due to this variance across the keys serious touch typists may find themselves with dropped keystrokes or that they are required to exert greater levels of force in order to ensure consistent typing, potentially resulting in tissue fatigue and damage to the fingers and hands.Ĭan Reduce Wrist Extension - The incorporated palm rest can assist in reducing the risk of Wrist Extension by keeping the wrists from dropping down to the desk or keyboard tray surface. The bottom row of keys (CTRL-ALT-EMOJI KEY etc.) is approximately 300% higher force than the letter keys just above this row. Key response is less distinct, requiring more sustained force, and varies at random across the keyboard, with even directly adjacent keys having noticeably different "feel".

While the Natural 4000 developed a reputation for its crisp and consistent key response, this successor fails in that regard. Please Note: Those familiar with the earlier Microsoft Natural 4000 Ergonomic Keyboard may find that the key action on the Microsoft Ergonomic Keyboard is significantly different that what they have experienced in the past.

Use of this lifter may require further adjustments of seat or keyboard tray height because it adds almost a full inch of elevation to the middle of the keyboard and increases the risk of a "pinch point" being created on the underside of the wrists. The keyboard also includes a detachable palm lift that can be used to raise the front to create negative slope intended to encourage better wrist alignment.

This elevation may require individuals to either raise their seats to accommodate the height of the keyboard or to use a keyboard tray to lower the keyboard into their lap. The minimum key height on this keyboard is 0.75" off the surface on which the keyboard is placed (1.75" on the keys in the middle of the keyboard). As a result it cannot be cleaned in the same manner as the leather-like pads on the Natural 4000.' However, unlike the pad on the Natural 4000, the surface of the palm pad on the Microsoft Ergonomic Keyboard is permeable. This palm rest offers improved cushioning and presents a deeper and flatter profile than that on the Natural 4000, helping to reduce wrist extension. An unusually deep 4" palm rest is permanently affixed to the keyboard. The left and right key groups are also splayed slightly outward to encourage a nominally more neutral alignment of the wrists. Ergonomic Benefits Features Images Additional Resources Specifications Usage Tips Models AccessoriesĪvailable in both English and French Canadian layouts, the Microsoft Ergonomic Keyboard bears design similarities to the Microsoft Natural Ergonomic Keyboard 4000, retaining the gull-wing design that orients keys at varying angles, from a maximum 14° tent in the middle to a traditional "flat" or 0° by the time the outer alpha keys are reached.
