Have you tried... WordPerfect? It still exists: https://www.wordperfect.com/en/product/wordperfect/
The first feature they list is Reveal Codes.
Personally I like Latex as it reveals all the codes and lets you type them, change them, find-and-replace them, define new ones, etc. But then, I'm a mathematician, so it's designed for my stuff.
