Forum:SH Archive/IMO or 1stm or 1stID?

Which of the above mentioned templates should be used, when the first mention of something is an indirect or a rarely used phrase? The LG is not clear enough. Examples:
 * Episode IV novelization mentioned Chancellor as President of the Republic. Is this 1stm and IMO? Or 1stID|President of the Republic? Or only MO (As President of the Republic)?
 * Episode IV novelization indirectly mentioned Order 66 "Having exterminated through treachery and deception the Jedi  Knights, guardians of justice in the galaxy". Is this 1stm and IMO? Or or only IMO?
