Reply To: Grep positive look behind at preceding paragraph

Not with this version of InDesign … (And I wouldn't hold my breath for the next either.)

The GREP styles are “just” some sort of fancy automated search-and-replace, so theoretically you can use the regular search-and-replace to fill in the character style you need. But it's not possible to do automatically.

Thought #1: ah, that dirty mind of mine! Change the paragraph return to a soft line break … (and don't do that if your text is justified…)

Thought #2: I have no experience at all with line styles. No idea why that would work, but — on the other hand, I've ben surprised before by off-the-wall tips with these.
