In their place, on the Natural Ergonomic 7000 keyboard, resides a single battery indicator light.The newest are the Sculpt ergonomic keyboard (2013) the Surface Ergonomic Keyboard (2016) and the Microsoft Ergonomic Keyboard (2019).
Ins moved to PrtScrn as the secondary function activated by F-Lock. It was designed for Microsoft by Ziba Design 3 with assistance and manufacturing by Key Tronic. The Microswitch division of Honeywell, which was responsible for that companys keyboards and was acquired by Key Tronic in early 1994, is also credited with design input. This key arrangement was ergonomically designed to prevent carpal tunnel syndrome and other repetitive strain injuries associated with typing for long periods of time. Another innovation was the integrated wrist pad helping to ensure correct posture while sitting at the computer and further reducing strain on the neck, arms and wrists. Microsoft soon asked Key Tronic to ramp up production to 100,000 per month in 1995, 33 and the Natural Keyboard sold over 600,000 per month at its peak. Over 3 million units had been sold by February 1998, when its successor, the Natural Keyboard Elite, was introduced. The first of these was the Natural Keyboard Elite, introduced in February 1998 at a retail price of US64.95 (equivalent to 102 in 2019). Like the original Natural Keyboard, the Elite was manufactured by Key Tronic, who also assisted in its development. Another common criticism of the Elite is that the arrow keys inverted-T layout has been changed into a cross-like layout, with leftright arrows keys side by side and updown keys bracketing them from above and below, increasing the distance between the vertical keys. Another significant change was the keyboards adjustable feet. While the original Microsoft Natural Keyboard had feet in the front to generate reverse tilt, the Elite and its successors have their feet in the back. The Natural Keyboard Elite was manufactured in at least two different color schemes; white with black lettering and black with white lettering. Microsoft Wireless Natural Multimedia Keyboard Software Is RequiredIn versions of Windows prior to Windows Vista, Microsofts Intellitype software is required to configure the behavior of the shortcut keys. Microsoft Wireless Natural Multimedia Keyboard Windows 7 Have TheVista and Windows 7 have the ability to customize shortcut key behavior without additional software when using the internet keyboard keyboard layout. Some other modern operating systems, such as FreeBSD and most Linux distributions, have comparable configuration options. The Natural Keyboard Pro also included an internal two-port USB hub, which was commonly used to connect other input devices such as a mouse or trackball, but this was dropped in subsequent iterations. Another common criticism is that although the bunched arrow keys of previous generation has been fixed by returning to the standard inverted T layout, the six-key navedit cluster has been changed to a 2x3 vertical layout, with Ins moved to the F-Lock function of PrtScnSysRq, and Del key expanded to double height. On the Natural Multimedia Keyboard, the status indicator lights for Num lock, Scroll lock, and Caps lock were moved from between the banks of alphanumeric keys to a more traditional location above and to the right of the backspace key. The Natural Multimedia Keyboard was manufactured in at least three different color schemes, including white with blue accents, black with silver accents, and white with black accents. The multimedia keys have again been redesigned, and the six-key navedit cluster has been fixed by returning to the standard 32 horizontal rectangular layout. The 4000 is also significantly quieter to type on, with less of the distinctive click clack noise that is common with older keyboards; as it is likely uses cheaper membrane key switches (as opposed to mechanical), which tend to be quieter but have twice as much travel before depression. The space bar, however, has been reported by several reviewers to be unusually noisy and difficult to depress. The 4000 is available in two variants, Business and Retail. The exact differences are not known, although product descriptions imply that the packaging is different, and prices are often slightly higher for the Business edition. On the Natural Ergonomic 4000, these lights are on the wrist rest, centered vertically under the spacebar.
