Well I wanted to enable handwriting but guess what... there were no instructions on how to use it. So I thought since I've figured it out. I'll write a guide.
First off enter System Preference
Next head off to Language and Text and then head to Input Sources
Check the languages you would like to write using the trackpad. In my case, Chinese.
Ok once you are happy with your settings hit
Ctrl + Shift + Space
A trackpad should pop up.
So how do we use it... mmmm...
Simple.
This is your trackpad
Imagine that that interface is directly on your trackpad! Simple as that!
Enjoy!
