I wasn't going to chime in on this thread...

My use of `C-o' is, well, peculiar.  I almost
don't use it.

I keep its default binding, which I never use
it for.  I use it only to try/test a command
I want to temporarily bind to a repeatable,
simple key that won't interfere with bindings
I really do use.  I do this (fairly often):

 M-x global-set-key RET C-o <some command
 I want to use temporarily, perhaps repeatedly
 (by just holding it down)> RET

Yeah, I know, seems a waste of such a simple,
repeatable key.  But it's precisely the
uselessness to me of that binding that keeps
the key free for me mentally.  In effect, I've
unconsciously tossed it onto the No-Default
Free List.

Needless to say, I do NOT want its default
binding to be changed to some command that's
useful but not repeatable.

I dread this thread, given that it has the
possibility that Emacs will change the useless
binding of `C-o' to some command that's useful
but not repeatable.  (Repeatable keys not at
the end of a prefix key are indeed rare).

IOW, it's a bad default binding, but therein
lies its usefulness: it could be worse.

[ The only reasonable alternative to binding a
  simple repeatable key to a repeatable command
  is to bind it as a prefix key.  That's what
  we've done for keys such as `C-x'.  That's
  OK.  But to bind a simple repeatable key to a
  command that, e.g., prompts for something is
  a mortal sin. Thou Shalt Not Waste. ]

If the default binding for C-o changed, how would your workflow change? Are you imagining we'd bind C-o to some *new* functionality for which we didn't have other bindings, forcing you to forego this functionality, change your habits, or bind the new functionality to some other key yourself?

I regularly use C-o. It’s pretty useful to add newlines without
automation which cuts in on pressing Enter.

Seeing how hard it is to agree on adding a new keybinding where none
exist, can we not descend into madness where we fload ideas to modifiy
things that have existed in Emacs since TECO days -- suggesting to
modify C-o is a hornets nest that one shouldn't touch.

To clarify: I started this `C-o` subthread for the sole purpose of
understanding what I'm missing.  I have no intention to change the `C-o`
binding (I'd even argue it's good to keep such a short "useless" binding
around since it acts as a kind of "user-reserved" key).

It isn't hard, at least not in this case.  You just sometimes need to
ignore messages posted here that don't affect the actual
decision-making process.

Don't worry, C-o will not be changed any time soon.  People can talk
all they want, it's a free forum.

Great minds think alike. ;-)

Same here.  It might also be useful to think about whether open-line can
be made more useful or DWIM-y in a way that doesn't break compatibility.

Many people mentioned the use of `C-o` specifically because it's not as
DWIMish as RET, so it sounds like it's probably better to leave
it alone.
