I've got a powerbook, so I only have the 4 arrows. I press the DOWN arrow to get to the end of a line immediately. that's about the only one I use. don't know if that helps you at all.
option + UP or DOWN arrows, moves a page (screen view) at a time
cmd + UP or DOWN arrows, take you all the way to the beginning of the text,or all the way to the end.
