» Low-Level Internal Key Numbers
Low-Level Internal Key Numbers are used to identify the individual keys/buttons on keyboards and mice. Generally speaking, the numbering matches the order of the keys on an Archimedes keyboard, from top-left to bottom-right. However, because keyboard layouts have changed over the years, not all keyboards will be capable of generating all low-level codes, and the interpretation of some codes may differ. Where multiple interpretations are possible, the Keyboard ID can be used to determine which should be used.
