FWIW, Option-left and Option-right do what you expect Ctrl-left and Ctrl-right to do.

As for why Home/End are virtually worthless keys, you got me. Though, since Powerbooks don't have specific Home/End/PgUp/PgDown keys (you have to do Fn-Left for home, Fn-Right for End, etc.) I think maybe they figured "let's make surethe same key combination can be used when people don't have full keyboards." That's just a guess though, it's more likely theyre just trying to be different.

My biggest disappointment with OS X Tiger is that they did little or nothing in the way of adding more keyboard shortcuts. Not necessarily Windows ones, but Windows-like ideas like the ability to use the keyboard to open menu items, sane keyboard behavior in modal dialogs, etc. Sometimes I think Apple needs to understand that just because Microsoft thought of it first (or copied it from Apple and made more use of it, depending on your religious beliefs) doesn't mean it's a bad idea.
