I don’t see KTV in the index (or Knight TV), but the space cadet keyboard has a lovely photo spread and two pages describing its effect on vi and emacs, its many modifiers and math keys, and some other facts. There’s two other small mentions; a pair of photos comparing its depth to an thin Apple Magic Keyboard and a homebrew keyboard inspired by it.

I took a flyer on this kickstarter and I’m really impressed by the results. It’s a beautiful labor of love. Incredible design and detail.
