> Attorneys and architects loved Word Perfect because it did line numbers better than any other software.
Lawyer here: I loved WordPerfect (for DOS) because of Reveal Codes and its easy keystroke macros, which let me write an Emacs keyboard emulator for it. (Yes, I eventually did one for Microsoft Word for Windows, which I use to this day.)
That sounds really cool. Have you ever shared it?
I posted the DOS version on CompuServe (!) probably 30 or 35 years ago. I don't think I ever posted the Word for Windows version. I switched to a MacBook a dozen years ago; I think I remapped some of its keys to emulate Emacs. (But in recent years I've used mostly Emacs itself and org-mode, because these days I'm mostly a law professor and use Word mainly in the occasional client contract-negotiation project.)
