Synopsis on corkboard cards

I keep forgetting how to do this. I want an automatically generated “synopsis” on the corkboard cards. It’s just a reminder and I NEED it. Just the first few lines… I know there’s a way… Can’t find it!

Scrivener 3 should automatically show the first few lines for you, unless you’ve deliberately entered a “blank” synopsis.

To auto-generate a “permanent” synopsis, use the Documents → Auto-Fill menu.
