The `SC` macro itself appears to be unique to this document in Unix V7, so I assume we can credit Brian Kernighan and/or Lorinda Cherry. I don't see it in other documents with a Kernighan byline, so maybe we can credit the late Ms. Cherry for it. It seems to have better ergonomics for latter-day *roffers who are more used to calling macros that take arguments than to ones which open a diversion and start gobbling up text for later regurgitation. The idea to leverage the groff `pdfbookmark` macro at that point, rousing the impressive machinery of modern PDF viewers, was all Deri's. Regards, Branden
