I offered Ward Cunningham's TECO page in my earlier message - which has one
of my favorite quotes:  *"TECO Madness -- a moment of convenience, a
lifetime of regret".*

I also mention Cantrell's C/UNIX version: Video teco
<https://streaklinks.com/Bm-JfYsNjZmndQ2FbAL4U22k/http%3A%2F%2Fwww.copters.com%2Fteco.html>

If this was someone using teco recently, Paul's version is possible/likely
as it was in C and became the teco many of used for UNIX.
For a while, I could never quite decide if I liked it more than vi, but
since ed and vi were >>everywhere<< from the Cray-1 to a PC, I stopped
using TECO as it sometimes took a little effort to make it work (although
Paul was pretty careful) - but particularly on non-UNIX boxes (other than
VMS) it might not be so easy.  Since Oscar's PiDP-10 and Angelo's PDP-1
work, I'll need an editor again, so I may have to relearn it -- be
interesting to see how fast it comes back. 🤔

For systems with a C compiler, Ward Miller's s (which is a subset of vi -
https://github.com/udo-munk/s) has been my go-to.
I was playing with getting it running on V7 since it full video for a
VT-100.
