I've certainly heard of them from multiple places. Also, ArrayForth uses them and the Forth code for the GA144 firmware has them (you can download it and convert to HTML). The basic idea was that you'd put your code in screens 2,4,6... and documentation in screens 1,3,5... and then your code editor would have a quick way to flip between a code screen and its shadow screen. Because of the low-resolution computer video of the old days, and maybe because of the 1K block size, traditional Forth screens were 16 lines * 64 characters. These days screens are larger and have more resolution, so you can write code and comments in a more interspersed and natural style.
