The keyboard includes the following groups of keys: Standard typing keys Function keys Special computer keys Cursor keys Numeric keypad Function keys for Windows interface Typing Keys The layout of the typing keys is similar to that of a typewriter. The standard typing keys are typematic; that is, they repeat typing the character as long as you hold them down. The home row contains raised identifiers for the touch-typist. Unlike some typewriters, "1" (one) and "l" (lowercase L) are not interchangeable on this keyboard. The Shift key is used with the typing keys to produce uppercase characters and symbols. When you press the Caps Lock key, a light turns on at the top right corner of your keyboard. When the Caps Lock light is on, the alphabet keys you type appear on the screen in capital letters. Caps Lock does not affect the number or punctuation keys. 22 I/O Features
