I don't have access to AmigaDOS so i don't know if that is true, but it seems plausible and i think would be convenient. I find the lack of prompt disturbing.
I note that in vi the prompt is the same key used to enter command line (:). Perhaps tine could use ␛ (this is U+241B SYMBOL FOR ESCAPE).
I see from https://wiki.amigaos.net/wiki/AmigaOS_Manual:_AmigaDOS_Using_the_Editors that on AmigaDOS: "To enter extended mode, press Esc. An asterisk appears as a prompt in the status line".
