I can’t answer your question, but will offer a remark.
I started off with WordPerfect, self-taught, and liked it. However, when I would send a WP document to a client as an email attachment, I would get a complaint that they couldn’t open it; my clients all seemed to be using MS Word. So I was forced to switch to Word to keep my clients happy. That was years ago.
It has been a long time since I have used WP, but at that time I did not have the impression that it was in anyway inferior to Word.
Same here. When I first joined the computer services staff at the governor's office, Word Perfect was the preferred application. Within a few years, we encountered the same problem exchanging documents between different offices and switched to MS Word.
One of the greatest features of WP was Reveal Codes. It opened a window into the code and streamlined the process of troubleshooting issues in lengthy documents. The same feature on MS Word is worthless. The big difference in approach between the 2 applications is in the approach to formatting. With WP, you "turn on" a feature (italics, bold, etc.) then then it off while you are typing. In MS Word, you format text and paragraphs AFTER you have completed the document.
