Now that tabindex can be used on any element to make it focusable, it makes sense that it should be possible to trigger a click on those elements with the keyboard.
Opera maps Enter to click. As far as I know, other browsers only do that for a few elements like<a>. What do people think? Should it be spec'd? At least the spec should say what elements map enter to click now. Except for perhaps<textarea> and a few form controls, I don't see why some should and others not, though. Maybe it should be a blacklist? - Aaron
