Who modded up this drivel? WordPerfect is a steaming pile of excrement and its market share was obliterated by Word for good reason.
The reason people liked the 'reveal codes' feature in WP is that you needed it to undo the clusterfuck WP regularly perpetrated on its own documents. The most common problem was incorrect nesting of code tags ([a][b] must be terminated by [b][a], not [a][b]). And woe betide you if you had a code tag that applied to more than one paragraph of text, good luck finding the matching start and end tags when they're 20 pages apart. If you were editing text and you accidentally deleted an end tag, your entire document fell over. This entire class of problems was eliminated by Word, which meant 'reveal codes' was no longer necessary.
WP shares Word's biggest failings: 1. making it easy to apply formatting directly instead of using standardized styles, and 2. making the layout printer-dependent. Choose another printer and watch the program fuck up your page layout.
Speed and ease of accomplishing things in WP? Someone who worked in WP all day for ten years could be fast. No faster than someone with the same experience in Word though. Features we take for granted in Word were painfully convoluted or entirely absent in WP. WP was severely lacking in discoverability and hostile to casual use.
