Yeah looks like you're right about at least the syntax highlighting and macros, I can't find any reference to Borland doing code completion back then and what I did find was people from much later complaining that it'd take up to 5 seconds to return suggestions, I used it around 4.5 and really don't remember any of those features though. I guess it was almost 30 years ago now though and I was mostly just interested in making the asteroids do weird things.

So replace Notepad with Notepad++ in my previous comments. There are definitely fast editors that do the same thing as Borland editors did back then the ones like VSC do a whole lot more and support a whole lot more.
