What kinds of keyboards are there?
The standard microcomputer keyboard consists of 104 keys arranged in the standard typewriter or QWERTY layout. A separate numeric keypad is at the right side of the keyboard and can be toggled on or off by pressing the “Num Lock” key. When on, the keys act like the keys of an adding machine or calculator; when off, the keys act like the arrow keys for moving the cursor around the screen. Special ergonomic keyboards are available (sometimes referred to as “Natural” keyboards) where the keyboard is split in the middle and the keys are rotated outward to reduce the risk of repetitive stress injury caused by prolonged keyboarding. Some keyboards include touchpads to remove the need of a separate mouse.
