A computer keyboard is a peripheral modeled after the typewriter keyboard. Keyboards
are designed for the input of text and characters, and also to control the operation of the computer.
Physically, computer keyboards are an arrangement of rectangular or near-rectangular buttons, or
"keys". Keyboards typically have characters engraved or printed on the keys; in most cases, each
press of a key corresponds to a single written symbol. However, to produce some symbols requires
pressing and holding several keys simultaneously, or in sequence; other keys do not produce any
symbol, but instead affect the operation of the computer, or the keyboard itself. See input method
editor.
Roughly 50% of all keyboard keys produce letters, numbers or signs (characters). Other
keys can produce actions when pressed, and other actions are available by simultaneously pressing
more than one action key.
