I must admit, I’ve never really been fond of sections as a way of organizing information. I find it takes too much effort to label them (I’m sorry I remembered F2 from Windows Explorer). But, for the life of me, I can’t figure out how you’re supposed to insert a section between two sections. You’ve got one collapsed section after another and you need to insert one between them. (I’m not trying anything fancy like sections embedded in other sections. I just want same-level sections.) How do you do it?

Working from memory here, so forgive me if this isn’t exact…
Use the arrow heys to navigate your cursor point to just before the second section, but still on the same line. Hit Enter (or Ctrl-Enter - this is the bit where I’m hazy.) Again, use your arrow keys to navigate back to the space you now have between them and insert your new section. The trick is to use your arrow keys rather than your mouse to navigate, as the mouse will activate the section.
Second (brute force) option: Cut your second section to the clipboard. Either leave it there and add your new section then paste the clipboard one back in, or paste it back further down and then insert your new section between them.
I haven’t had to do this for some time now, so caveat emptor

Ooh! I’m so used to the mouse that I never considered using the keyboard. Your advice worked fine. Thanks!
