You can use Control-down-arrow and Control-up-arrow to move by pages, and Command-up-arrow and Command-down-arrow like Home/End. But note it is technically possible to remap key bindings for text fields in any way you want. Here is one article about it: http://www.hcs.harvard.edu/~jrus/site/cocoa-text.html http://www.hcs.harvard.edu/~jrus/site/cocoa-text.html Basically, Cocoa methods exist for almost any imaginable text editing action (such as pageDown), and they can be mapped to any keys. I would also imagine there's a way to map them to gestures on the MacBook's trackpad.
