Reveal Codes was my favourite WordPerfect feature. (I'm not a lawyer though.) It wasn't so much that it revealed how things are represented, because the coding was simplistic enough that there wasn't any real underlying representation as such separate from the document formatting - it simply told you where regions of one style began an ended. Like looking at an HTML document in View Source mode. You could have half the display dedicated to Reveal Codes, as I recall, and edit in either mode as you went along (a bit like Dreamweaver). Made it super-easy to keep things in line. Word, by contrast, makes it very unclear where one format begins and the next ends, meaning it's all too easy to make a mess. (Back when I still used Word, though maybe they've fixed it by now, it was very common for the space after the last character in a page before a manual page break to have the format of the following page, for example! Caused havoc when trying to style the last sentence...)
