I have to agree with the Eng./Mktg. discussion for item 1. I've heard about studies that said it was a double-edges sword for useability.
On the other hand, Item 2 might be an oversight, and might be added some day. It's not obvious, since AFAIK, almost no one uses the similar Windows shortcuts.
On the gripping hand, "Of course it's perfect the way it is you idiot. It's just for reading, stop picking at it and read." Oh, and by the way, "Don't read in the dark you moron, you'll ruin your eyes. Turn on a light."
