I remember using:
0lt$$
(the $$ is how escape-escape echoed.)
More times than I can count... but then again, it's what you had to do when
programming on a teletype.
The ed and vi commands are actually based upon TECO. As far as I know vi is
just a visual decedent of TECO.

IBM-MAIN relevancy: ISPF EDIT still rules! (But now I should learn
regexps.)
I never tried TECO, after reading "Real Programmers Don't Use PASCAL"
40 years ago. Extract:
Some of the concepts in these Xerox editors have been incorporated
into editors running on more reasonably named operating systems -- EMACS and VI
being two. The problem with these editors is that Real Programmers consider
"what you see is what you get" to be just as bad a concept in Text Editors as
it is in women. No the Real Programmer wants a "you asked for it, you got it"
text editor -- complicated, cryptic, powerful, unforgiving, dangerous.
TECO, to
be precise.
It has been observed that a TECO command sequence more closely
resembles transmission line noise than readable text [4]. 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.
