Yahoo KeyKey 2 v2.6.3

• Faster startup and lower memory use. At launch, Yahoo KeyKey 2 no longer builds a large in-memory copy of its whole dictionary just to work out which characters are most common — it now reads only what it needs. The app starts up quicker and uses less memory, and nothing you type changes.
• 拼音 typing is a little more efficient. While you're composing pinyin, the engine skips repeated sorting work it used to do on every keystroke. You'll notice it most with long phrases. The candidates you see, and their order, are exactly the same as before.
