There are lots of free browser-based programs that will teach you how to type. Here's a website that is an online game which helps develop typing skills.
typing.com also seems pretty straight-forward.
Is there any great software that teach me to blind touch (type without looking at the keyboards)?
In 8th grade, I finally could type without looking at the keyboard using typing.com -should've learned by 4th, but my teacher made us use a unnecessarily complicated program. Typing.com looks like the simplest one to me.
