- There are editors with key bindings similar to Wordstar, like JOE.
- From what I remember of Wordstar, it used formatting commands which begin with a period on a new line ("dot commands"), such as:
.op
to "omit page number". That's reminiscent of troff, which also has dot commands. So basically, I suspect you could have a "vaguely Wordstar-like experience" if you learn a few troff dot commands and use JOE to edit the text. Of course external tooling is used to compile the troff to PDF and whatnot.
- There is also something called Wordtsar: http://wordtsar.ca/ This looks to be a Wordstar clone that the author mainly develops on Linux.
Hey look, someone in May 1985 was asking in comp.unix.wizards if there is a way to convert Wordstar fiels to Troff.
That would be right around the time I would have been typing out grade 8 homework in Wordstar, running under CP/M via a Z80 coprocessor card inserted into my Hong-Kong-made Apple II+ clone.
