Oh yeah. I'm going to date myself here, but I was just going to say this reminds me a lot of Borland Turbo C++ way back in the day. They had this thing called Turbo Vision for building text UIs. It seemed super cool back then.
Though the integrated help really improved with version 6 (when Turbo Vision was also introduced) since you could move a cursor freely inside the help window as if it was an editor, select and copy text, the help text was much more detailed and more organized and every function/procedure also had a small example showing its use (version 5.5 also had examples but the overall help was much more terse).
