keyboard layout

The 104-key US QWERTY layout A keyboard layout is any specific physical, visual, or functional arrangement of key switches, legends, or key mapping (respectively) of a keyboard. Layouts are used on computer keyboards, for virtual keyboards (including mobile phones or other touchscreens), or other typographic input devices. Standard layouts vary depending on their intended writing system, language, and use case. Some hobbyists and designers create alternative layouts to better suit individual preferences or to extend functionality.

Layouts can be described in several ways depending on form or function. A physical layout is the positioning of physical keys on a keyboard. The arrangement of keycap legends, such as markings or labels, is described as a visual layout. Keyboard mapping represents a functional layout, or the association of keys with their action when pressed. This is configured in software or firmware, and determines the action upon one or multiple key presses, regardless of key appearance.
