Take Control of Scrivener 3 (p. 11) assures that in Scrivener 3 Index cards on the Corkboard and rows in the outliner now show a preview of the first words of the main text if no synopsis is assigned.
My Scrivener 3.0.2 does not do that. Have I missed something?
The official term for this is evidently “adaptive naming”. You can read about it in the Scrivener 3.0.2 manual starting on p. 113. AFAIK, there’s no preference to control this; it’s truly automatic–but you have to be sure the title and the synopsis are really empty; a leftover space or a return character will keep this from operating. Here are a couple of screenshots:
Huh, you learn something new every day. “Adaptive naming,” eh?
Dude. It’s in your manual… 
Like anyone tells me anything. 
So you’ll be delighted when you find out that Ioa has committed you to including a complete Vim compatible text engine for V3.1?
For the original poster, HOV, I should add that for some odd reason, the adaptive synopsis won’t show in the outliner if the document has a real name—unless the outliner is in fixed row height mode.
Well, now we find out it’s not KB’s manual, it’s Ioa’s manual!
You’re surprised by this?
The real question is whether it’s actually a functional spec disguised as a manual.

I really shouldn’t be, but I am.
Floor wax AND desert topping!
Yep, Ioa took over the manual completely from some time around version 2; he’s a brave man. He usually discusses terminology with me, but he obviously got creative on this one. 
(Or he discussed it with me and I forgot - that happens a lot.) And one of his favourite tricks is to email me saying, “I described this feature in the manual like this - now can you make it work like that?” - he’s sneaky like that.
I’ve always treated it as such…
