Can't find it. Apologies if I missed it somehow.

In EDT there actually is a workaround, but it's not pretty:

*QUIT/SAVE

Open the journal file in EDT. Press ESC and then the defined key you regret you pressed for each such key to see what its translation is. Delete that. Delete your goof(s) at the bottom and exit.

Then open your file again in EDT, but this time with the /RECOVER qualifier.

Yeah, pretty clumsy, but it works!

Is there anything like this for EVE or TPU or whatever? An actual built-in UNDO command or some workaround like the above? (Apologies if I missed it somewhere.)

And yes, EVE's QUIT "Are you sure . . . ?" bit is pretty good. as QUIT in EDT can be ruinous.

Just curious. Please, let's not start an editor war. I already know EVE/TPU/LSE and other whiz-bang editors have lots of stuff EDT doesn't. I know. I acknowledge it. I am not claiming otherwise. I am asking ONLY about UNDO capability. Thanks!

I have never heard about it and I can't find it in the docs either.

And I have been using EVE for 34 years.

Looks like LSE has it, but not TPU! I don't see why that should be!

I'm a bit surprised TPU/EVE/whatever doesn't have it. You'd think that it would be a rather popular feature! I mean, UNDO is rather common among many editors or apps like non-linear editors (NLEs) like Final Cut, for instance..

Both TPU and LSE have it - just load either, then use RECOVER BUFFER -

I've used the QUIT/SAVE and editing the .JOU file then EDIT/RECOVER
maybe two or three times in my life. I usually don't need it. Quick
edit? Just revert to the previous version of the file (and silently
mock those who don't use VMS).

For longer editing sessions, I periodically save the file without
exiting. I do this in order to recover in case of a bad edit, but with
LaTeX, Fortran, etc., I like to compile frequently so that I catch any
typos. Actually, for long sessions I use the command file below. I've
defined GOLD-W as "EXT WRITE EDT_FILE." to make it quick.

$ DEFINE/USER_MODE EDT_FILE 'P1'
$ FILE = F$ELEMENT(0,".",P1)
$ TYPE = F$ELEMENT(1,".",P1)
$ JFL = FILE + "_" + TYPE
$ LEN = F$LENGTH(JFL)
$ IF LEN .GT. 39
$ THEN
$ START = LEN - 39
$ JFL = F$EXTRACT(START,39,JFL)
$ ENDIF
$ JFL = JFL + ".JOU"
$ IF F$SEARCH(JFL) .NES. ""
$ THEN
$ WSO ""
$ WSO "%EE-W-JRNLFE, journal file exists"
$ DATE = F$FILE_ATTRIBUTES(JFL,"RDT")
$ DIR/DATE=(C,M) 'JFL'
$ DIR/DATE=(C,M) 'P1'/SIN="''DATE'
$ DIR/DATE=(C,M) 'P1'/BEF="''DATE'
$ READ/PROMPT="Do you want to recover (Y/N, default is Y)? " -
SYS$COMMAND ANSWER
$ ANSWER = F$EXTRACT(0,1,F$EDIT(ANSWER,"COLLAPSE,UPCASE"))
$ IF ANSWER .EQS. "N"
$ THEN
$ EXIT
$ ELSE
$ @ PROZDIR:RECOVER.COM 'P1'
$ ENDIF
$ ENDIF
$ DEFINE/USER_MODE SYS$INPUT SYS$COMMAND
$ DEFINE/USER_MODE EDT_FILE 'P1'
$ E/JOURNAL='JFL' 'P1'
$ EXIT

RECOVER BUFFER recovers via journal file.

But how do you tell it to skip last change or last N changes?

Flippant answer: Yes, there most certainly is. Just save your work
very frequently and then use the multi-version capability of VMS
to roll back to the file version before you screwed up. :-)

Serious answer: Not that I am aware of, apart from the usual one level
of undelete if you press remove or delete character/word/line by mistake.
There's nothing like the Emacs undo functionality in EVE that I am
aware of.

LSE has an actual UNDO command. I tried it and it works. But it's not bound to a key. Anyway, looks like EVE/TPU doesn't have it. Thanks all.
