tsInputModeJISKeyboardShortcutKey property of input mode indicates JIS key to switch input mode. Its value is defiend as following:

 * 0=none
 * 1=hiragana
 * 2=katakana
 * 3=eisu

(quoted from: /Applications/

Modern JIS keyboards of Mac have hiragana key and eisu key. However, it does'nt have katakana key.

To avoid confusing, it is good to mark katakana key as deprecated.
