Line break in notes

Newbie question: I’d like to place a line break in a note. When I hit “return”, I get a new note. Are line breaks not possible in notes?

Preferences > Behaviours > Return Key

You can also use Opt-Return to enter new lines in the synopsis, if you prefer to keep the default Return behaviour. Opt-Return also lets you type a carriage return in fields like Find and Replace or compile replacements.
