/** Keycode definitions.
40
* A keycode identifies a key by its position on the keyboard, rather
41
* than by its label. For human readability, key positions are noted
42
* with the key label on a keyboard with US layout. This label has
43
* nothing to do with the character, that the key produces
44
* -- this is determined by the keymap.
46
* The keyboard model reflects a standard PC keyboard layout.
47
* Non-standard keyboards need to be mapped to this model in some
48
* logical way. Scancodes are mapped to keycodes with a scanmap.
50
* For easier mapping to the model and to emphasize the nature of keycodes,
51
* they really are organized here by position, rather than by label.
