Review request for MACOSX_PORT-369: UnsupportedOperationException is thown on getLockingKeyState()

[Andrew Thompson]

Kana lock implies switching the keyboard to the mode where it enters Japanese Kana characters. It's probably the key to the right of the spacebar in this screenshot: http://en.wikipedia.org/wiki/File:MacBookProJISKeyboard-1.jpg. The key labeled かな and カナ, which both say 'kana'. I'd be surprised if it is a lock like caps-lock though. I've never used a physical Apple Japanese keyboard unfortunately, but I would be surprised if that key works like caps-lock.  Most likely it cycles through multiple modes.

As for Num Lock, the key located at the same position on Apple keyboards as Num Lock on PC keyboards is called Clear, doesn't lock anything and is used for entirely different purpose. Kana Lock is a mystery to me: I'm not an expert in I18N, so I've plugged in that ancient Japanese PC keyboard we have in our office, but it looks like OS X ignores Kana Lock key on this keyboard and doesn't generate any key code we can check.
