> Syntax highlighting six years before the invention of vi(1)? > That's indeed a funny idea! People were really creative at the time in making maximum use of the technology available to them. Teletypes had the ability to underline and embolden by overstriking, and this was indeed used not merely for highlighting but as actual part of the syntax when entering code. For example, some dialects of Algol allowed stropping by underlining, and Mirfac (because it was mentioned previously on this list) allowed the use of "red ribbon" for "comments and also for those functions whose names are combinations of English letters". (In printed matter, such as in academic journals, Algol traditionally used boldface for highlighting keywords.)
