I did not know about Shift-Opt-O for example.

Insert the character 'Ø' into the source file??? I was not trying to do that!

Very good. Like the typeset version of \O much better than \emptyset.

Did not know about Opt-= producing ≠ at least here in Mail.app.

That's the shortcut I alluded to, although I also include \ensuremath so that \N works well in text mode. However, I misjudged that the equivalent could be done with the Key Bindings Editor.
As always, thanks for you help.
