Laptop keyboards

A laptop keyboard is arranged differently than a desktop keyboard to accommodate the laptop’s narrower footprint. Most laptop keyboards are made smaller by placing the keys closer and by including an Fn key. The Fn key is used in conjunction with other keys to perform special functions. For example, pressing the Fn key and the up or down arrow on the keyboard shown below, increases and decreases the brightness of the screen. Furthermore, many laptop keyboards omit the numeric keypad to save space.
