Yahoo KeyKey 2 v2.6.4

• Starts up even faster and lighter. At launch, Yahoo KeyKey 2 now reads its dictionary in a single pass instead of two, and it builds the 速成 (Simplex) code table and the 反查／拆碼提示 reverse-lookup index only when you actually use them. If you type only 倉頡 or 拼音, that's less work and less memory every time the app starts. Nothing you type changes.
• 拼音 stays responsive on unusual input. Typing a long run of letters that can't form valid syllables no longer makes the pinyin composer do more and more work on every keystroke.
