OS X dialogs: Can I use 'Enter' to invoke the *currently selected* button instead of the default one? In an OS X dialog, there a way to make 'Enter/Return' invoke the currently selected button instead of the default one (and, if possible, make 'Space' invoke the default button instead). That is, can I swap the behaviors of 'Space' and 'Enter' in this situation?

[This would keep this behavior consistent with that of the web's, and other platforms like Windows and Linux]

Also, I use KeyCue to find most-if-not-all shortcuts in any context.
