fixing Home and End keys on OS X

Recently at home I've started plugging in a full-size keyboard to my MacBook Pro. The default behavior of the Home and End keys on OS X (go to the beginning/end of the document) is totally counter-intuitive to years and years of muscle memory built up on Windows (and now Linux), to go to the beginning or end of the current line.

I found KeyFixer today and installed it. It's been a lifesaver so far - now my Home and End keys work the way I expect. Now, I just need to figure out how to remap Ctrl-left arrow and Ctrl-right arrow to jump to the previous/next word, and I'll be all set!
