Positive key codes for any of those keys constitute a violation of the MIDP specification (except perhaps mapping clear to \u0008) --- From the spec: "For keys that have no corresponding Unicode character, the implementation must use negative values" Abbreviations:

  • NSK: Device has no such key
  • TA: Key terminates application
  • BG: Moves application to the background
  • NSP: Phone has this key, but it is not supported (does not generate a Java key code)
  • JP6+: Sony Ericsson Java platform 6 and higher
Key Names:
  • CK: Center Key (5-Way navigation center click, sometimes labeled "OK")
  • LSK: Left Softkey
  • RSK: Right Softkey
