What Is A Keyboard? computer keyboard
The regular function of the 7 key, for example, is to input the number 7, but if you hold down the Shift and 7 keys simultaneously, the ampersand (&) sign is produced. Some keys you should become familiar with are called modifier keys. You’ll probably see some of these in the troubleshooting guides here on this website; the Control, Shift, and Alt keys are modifier keys. Mac keyboards use the Option and Command keys as modifier keys—see Windows Keyboard Equivalents for the Mac’s Special Keys for more on that.
Switching to a much more ergonomic mouse, such as a vertical mouse or joystick mouse may provide relief. The use of any keyboard may cause serious injury to hands, wrists, arms, neck or back. The risks of injuries can be reduced by taking frequent short breaks to get up and walk around a couple of times every hour. As well, users should vary tasks throughout the day, to avoid overuse of the hands and wrists. When inputting at the keyboard, a person should keep the shoulders relaxed with the elbows at the side, with the keyboard and mouse positioned so that reaching is not necessary.

However, the lack of privacy when issuing voice commands and dictation makes this kind of input unsuitable for many environments. But lower-quality keyboard designs and unknowledgeable engineers may not know these tricks, and it can still be a problem in games due to wildly different or configurable layouts in different games. The first electronic keyboards had a typewriter key travel distance of 0.187 inches (4.75 mm), keytops were a half-inch (12.7 mm) high, and keyboards were about two inches thick. Over time, less key travel was accepted in the market, finally landing on 0.110 inches (2.79 mm). Coincident with this, Key Tronic was the first company to introduce a keyboard that was only about one inch thick.
