I just got my macbook a few days ago.....Does anyone know if there is an "end" feature or a "home" feature on macs?? It's kind of annoying to not be able to just hit a button to get to the end or beginning of a line while typing. Nothing major, but it would help if I knew where it was if there is one. Thanks!! Also, what does the FN button do in the lower left hand corner on the keyboard?
