I never learned to touchtype on qwerty and earlier this year I switched to colemak and am now touchtyping at about 75 wpm. I am in my third semester of Chinese in college and so occasionally have to type in Chinese. I am on Windows so I can easily use the built in language tools. My only problem is that it seems that I can only use qwerty. This makes typing in Chinese painful and I have to look at my keys going very slow. I am already not very good at Chinese, I don't need my keyboard making it worse. Thanks for your help.
Edit: I am using Windows 7.
