If you want to input a word with two chinese characters, like DanXin,
just type danxin and hit "space" key twice if it is the first in the list,
if it is the second, hit the number key once following by a "space".

Try F1 when you are not sure what one character's pinyin is or its WuBi code is.

Sometimes F2 could help too (when you have both PinYin and WuBi turned on)
