You’ve improved the documentation a great deal. Thank you. A couple of comments:

1. In GETTING STARTED (and following), you use double curly braces rather than the default delimiter of % characters. When you get to the screenshots, they show %s, and no sign of the curly braces.
2. In the easy-peasy 1-2-3, you refer to the “Custom Fields meta box” without mentioning where that can be found. (That was the nut of my problem.) Later on, under the “I CAN’T FIND” them heading, you mention “they should appear at the bottom of the editor screen.” That should be said in the 1-2-3, I think. (More about the trouble I had in this regard, and a question below.)
3. The screen shots are unreadably small on my display. (Big screens, old eyes.)

In case it’s useful, more about my confusion: I was coming in cold to a twice-cloned site that someone else (now dead) had created, and someone else had cloned and modified. Quite a long page. The multi-pane WP page edit UI creates layers of obfuscation, with funky scrolling. Scrolling to the end of the content, the next thing is the Revisions history, which was very long. Then finally, the Custom Fields block, which had four entries starting with “vantage_” and no sign of the mystery %CODE2% (at the very top of the content), nor %CODE1% at the bottom.

I did find the Code Embed Search form, and could see the javascript blocks that were indeed being rendered into the page. Using it again just now, it finally makes sense: these two codes are defined on ANOTHER page in the stack (happens to be from the first clone), rather than the page I was editing. The code identifiers are GLOBAL–as you note in your “Key features.”

I’m left to wonder what happens if I (re)define CODE1 on this page. (Can I define the same variable on multiple pages?) What seems best is to MOVE them from clone-1 to this, clone-2, so that the next new person might find them more directly.
