In WordStar it's a little more nuanced than that.

First, it's properly ^K X, as the ^K prefix subcommands block/file actions, as written by Rob Barnaby into all the WordStar versions starting with CP/M.

Second, ^KX as 'exit' means to save the latest revisions out to file before quitting, while ^KQ, 'quit', means to abandon the revisions. You might get a confirmation dialog and a chance to change your mind before you're dumped back to the commandline.

Current-convention iconic close-window behavior more closely emulates the latter.

Correct on the commands while editing a document, but I was specifically referring to the WordStar start screen before one begins editing a document (check the flickr link) where it has "X EXIT to system" (the all caps is also in the screen shot).

On WordStar 7.0a for dos, the main start screen menu selection is "X exit WordStar".

I think Turbo Pascal worked that way too
