The keycodes component of a keyboard mapping specifies the range and interpretation of the raw keycodes reported by the device. It sets the keycodes symbolic name, the minimum and maximum legal codes for the keyboard, and the symbolic name for each key. The keycodes component might also contain aliases for some keys, symbolic names for some indicators and a description of which indicators are physically present.
