Me too until I found that Fn+Up/Down,Left/Right do what you want. Also Fn+Backspace to delete.

Tip: You can use KeyRemap4Macbook [1] to map the stupid eject button on MBP to delete. And if you use vim, you can map Escape to Delete and vice versa. Very useful.

That's a poor substitute. These tiny arrows are hard enough to hit on their own. Chording doesn't make it better, especially since often you need Shift-PGUP, Shift-Home etc.

Fn+backspace to delete is a new trick for me! Thanks a million!
