Two different names, from different traditions, for naming a constant-width typeface. (In groff, or any device-independent troff taking a cue from PostScript, more than one constant-width face is available on typesetting devices, and you would write 'CR' instead of 'C' or 'CW'. But ultimately what faces are available depends on the device for which you're formatting. In the groff 1.23.0 man pages, this matter is much clarified. See its grodvi(1), grohtml(1), grolbp(1), grolj4(1), gropdf(1), grops(1), grotty(1), and gxditview(1) man pages. Not too long ago I discovered what I think is the ultimate origin of `CW` usage as a face name, in the Unix System III manual. I'll follow up with more on that as time permits. In man pages, no face names are truly portable apart from 'R', 'I', and 'B'. That's what existed in 1979. You can do sneaky things beyond that, and I have. But those are the ones you can count on.
