I started with TECO (Text Editor Character Oriented) on Caltech's PDP-10 back in 1975. There were no glass ttys, just DECwriters and ASR-33s (ugh). I.e. TECO was a line editor.
A couple years later, ADM-3A's arrived. And so did a TECO macro that turned TECO into a screen editor! Oh, what joy!
Isn't it a amazing that a macro could turn a line editor into a screen editor?

I also used TECO on my H-11 PDP-11 computer.
