Learning to use computer without mouse?

I am looking for some advice how to learn to operate computer with keyboard only. I find it much faster if you know all the shortcuts / tricks etc...

EDIT:
I found some interesting links, they are below:

If enough people get interested in this post, I can turn all my findings into a nice post.
