Time as an FO in the 121 world for an aircraft requiring more than one pilot is only SIC time, regardless of who’s actually flying. Unless your captain is incapacitated... In that case you should determine if they’re senior to you or not. If they are, reduce thrust and start the clock.
Just kidding...
Edit: The grey area regarding “sole manipulator of the controls” may allow you to log that time, but you’re still not acting as PIC in the 121 world. The lawyers would have a field day trying to sort that out if it ever came down to that... not a can of worms worth opening IMHO.
