  39.  *
  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.
  45.  *
  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.
  49.  *
  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.
