Introduction
In double pinyin mode, user would type two keys (one for consonant and the other vowel) for a single Chinese character, the first is an initial consonant and the second is the simple or compound vowel. For example, assuming the default double pinyin scheme is adopted, "一只可爱的小花猫" can be typed using "yivikeoldexchwmk".
