What did I do to my outliner view?

I was looking at my novel in the outliner view and I added a few columns, etc…

And I guess I clicked on Title and Synopsis.

So now all the sections are listed alphabetically. I want to go back to them being listed chronologically/numerically and I cannot for the life of me figure out how to do it.

…and I have discovered that closing the document and reopening reorders the outliner.

Is there any way to do this short of closing and reopening?

Just click on Title and Synopsis repeatedly and it toggles through a few views:

• A—Z
• Z—A
• Binder order
