Oh... silly.
Those ARE Page Up. Page down. Home and End. They just dont Type out the words and make it look ugly. But they DO the same things.
Use normally will move the scroll but not the cursor. Used with the Option key will jump the cursor, like old WIN 95/XP.
Enjoy.
Just an observation, not a criticism. I shouldn't have called you a "fangrrl," I know how that peeves people. I don't personally have an OS preference. I regularly use Windows, Mac, UNIX and Linux.
