The keyboard is an input device used to type documents, access menus, play games, and perform other tasks. It contains keys called keycaps that are arranged in a QWERTY layout on most keyboards. Keyboards standardly have around 100 keys organized into groups for alphanumeric keys, numbers, functions, modifiers, and cursor movement. Ergonomic keyboards are designed to reduce injuries from long periods of use by keeping hands farther apart and aligned with the forearms. Variants include illuminated keyboards with light-up keys and customizable keyboards like the Optimus keyboard.
