Use of :@ on mode line

Use of :@ on mode line

[Kevin Buchs]

I'm running GNU Emacs 25.1.1 (x86_64-apple-darwin15.6.0, NS appkit-1404.47
Version 10.11.6 (Build 15G1004)) graphically and since I started running
it, I'm seeing an extra character on the mode line. Where there was just a
colon between CS and CH, there is now :@. What does that mean? It isn't
documented in the Info manual:  (info "(emacs) Mode Line") nor do I see it
in the What's changed section of the Info manual.

 Example mode lines:
  - Reading an Info page in info-mode:   U:@%%-
  - Buffer created and changed: U:@**-
  - File opened and unchanged: U:@---

Thanks,
Kevin Buchs

It's quite possible that just hovering your mouse pointer over those characters
tells you more (I don't have an @: here, so I can't say)

Crystal ball says you are running via emacsclient, perhaps your Emacs
is a daemon?

This character indicates that the frame was created by emacsclient.
You are right, it wasn't documented in the manual that shipped with
Emacs 25.1, but it is documented now in what will shortly become Emacs
25.2.

Not the OP, but... thanks Eli! Now that I know what to look for, I can
make one myself :-)

And in fact, hovering over the @ says "client frame": for a "newbie"
perhaps a bit concise, but loud and clear.

Thanks, Eli and Tomas. I honestly would never have guessed the documentation would be in a mouse-over. I am thinking that in the examples I cited, none of those were opened by emacsclient. Perhaps it does have to do with the strange way things start on the Mac.
