Scrivener newbies, here's one of my favorite tricks -- useful for getting started on a new project, and good for those who are allergic to "outlining." Create a blank document, then write a barebones summary of the argument you wish to present or the story you want to tell. No elaboration, just the basic ideas that you want to cover.
Now, at the beginning of each sentence, create a new section by putting your cursor and then hitting Ctrl+K (If you wish, select some text at the beginning of the sentence, and hit Ctrl+Shift+K -- The selected text will become the section title). When you've done this with every sentence, switch to Corkboard view -- there's your outline on index cards. The cards will be blank, except for the heading (if you used Ctrl+Shift+K) -- to fill them in, select a card, look at the representation of the card in the Inspector panel (right side of screen), and hit the little auto-generate button -- it will fill in your sentence on the card. Use the other index card features if you like -- I use label colors to indicate larger sections, and status marking to help me track which parts need to be revised (I customize both to suit my needs).
Use Corkboard or Outline view at any time to rearrange your thoughts, or add new ones -- you aren't hampered by any hierarchy. Get things into the order that makes the most sense to you.
Now, you have a fully-functioning outline without the rigid hierarchy that "outlining" implies (remember those high school exercises in outlining? Yuck.). Go back to scrivenings view (text) and write each section, filling in & elaborating your ideas. When you get done, you'll have a well-organized first draft. To save the draft before revising, take a Scrivener snapshot. Easy peasy.
Here's a short story I just started. I had the general shape in mind, wrote it out longhand, and used the shape of the hero's journey to make sure my plot had a satisfying arc to it. Then I just transcribed the written outline into Scrivener and followed the steps I just mentioned. I am good to go! I do this for my blog posts, too.
