What I'm curious about is why EDT never appeared
under RT-11. (or did
it?)   KED is respectable, but EDT is pure heaven. 
   I agree - my favorite editor.   But, the first version or two, as delivered with RSTS
at least, was a hellish mode based thing - like VI, you had to constantly switch between
insert and edit modes, and if you forgot which mode you were in and hit a keypad key at
the wrong time, all hell would break loose.
   I tried it and used EDI instead, until the later version of EDT came out - limited as
EDI   was, it was far more predictable and didn't tend to go wild as easily.
