I often look up things as I jump between a couple different languages depending on what I'm working on. I'm not really looking how to do things, but more like how something worked, or maybe a more efficient way to do something. Usually if I'm going to copy/paste something it's just to paste into my code as a comment to use as an example. If I had to program without access to the internet, I'd need to have reference books around or I'd get stuck pretty quick.
