Can somebody without More Add-in installed see what's inside a closed collapsible?

If you send a document with collapsibles in it another user, but they don't want to (or can't) install More Addin, they can still see the body or "content" of the collapsibles.  

There are two ways.  Both take advantage of the fact that collapsibles work by exploiting Word's "hidden text" functionality.

1. Click on the "Show paragraph marks and other hidden formatting symbols" button - i.e. the button with the funny backwards-P on it in the Paragraph group on the Home tab.  This shows hidden text. 
   • Pro: quick and easy.
   • Con: Page looks awful, because so much other "rubbish" is displayed at the same time.
2. Tell Word to always show hidden text by going to Word Options > Display and checking the appropriate box.  
   • Pro: Mores look better, though there is still dotted underlining in the collapsible body
   • Con: takes more effort and know-how to show the collapsible body, and hide it again. 
     • Tip: Add a button to your Quick Access Toolbar enabling you to do this in one click.

Both of these are "all or nothing," i.e. you show all collapsible bodies in the document at once.
