Have been using TK for about four decades of writing, not sure where I picked it up from. An editor who was working with me in my teens I think. More so recently (the past 20+ years) [todo] and [info] and [note] when I have a tangential thought that I need to return to. Interestingly, during an interview with some of the writer's of Star Trek: The Next Generation, or perhaps even Levar Burton, they mentioned that many of the scripts would simply have "TECH" in them for inserting random, technically plausible sounding gibberish that didn't advance the story but could be set aside as a decision point whilst working on the script.
