Ok, maybe I'm just one of the few people who have missed this feature. But I accidently hit the F7 button and a dialog box asked if I wanted to enable Caret Browsing, a moveable cursor on the page that allows you to select text with a keyboard.
Does anybody else know about/use this? Like I said, I'm probably one of the few people who have missed this feature, but I don't remember seeing anything on the forums about it.
