Hi! First of all, I have to say Org-mode rocks. I am a law student. I have been using Org-mode for my case brief, notes, and most importantly, the outline for certain area of law. One question I had is that I am not sure if I could choose to export only headings to a PDF file. For example, I want to export everything above Level 4 and I don't want details below Level 4. Can I do that? Thanks! Best, Ning
