It has been observed that a TECO command sequence more closely resembles transmission line noise than readable text. One of the more entertaining games to play with TECO is to type your name in as a command line and try to guess what it does. Just about any possible typing error while talking with TECO will probably destroy your program, or even worse - introduce subtle and mysterious bugs in a once working subroutine.
I've used TECO for a few months in my first job as a computer programmer. Back then, it was the best editor they had. No, I didn't destroy any documents with it, and my name didn't do anything in TECO. (Of course I checked, but I don't think "k" was a TECO command!) A few months later, they got EDT [wikipedia.org], a full screen editor, after an OS upgrade, and line-based editors, such as TECO, were abandoned. I became proficient in EDT, and even wrote a set of EDT emulation macros for vi, when I started using Unix.
I moved on to using TPU [wikipedia.org]/EVE [wikipedia.org], including some programmatic stuff where call handlers could edit case-logs, able to view the entire log, but only able to append to the end of it while still using the familiar text editor they were used to using. I liked EVE.

EDLIN? Why not sed? (Says the TECO user)
