I plan on working with an editor. My book is in many small parts on Scrivener. The editor does not have a Mac (and can’t run Scrivener). The book is not finished so I don’t want to export it and then just work from word. What would be the best workflow for working with another person?
Usually editors at publishing houses want to see an entire draft, not bits and pieces. If by “editor” you mean a collaborator who helping you edit, the quickest way to move a piece of text in Scrivener is: put the cursor inside the item, Copy All, then open a window in Word and Paste. Mail that file to the editor and ask him/her to Track Changes. You accept or reject the changes, then drag the Word file to Scriv. You could label each revised chunk with a -rev suffix, like ch 1-rev. [Amber is right; check the forum for many other tips about export and import.]
