Background editing

[Angel M Alganza]

Hello,

I said in a previous email I was wondering what other great things might
be "out there" waiting for me to be discovered.  Well, while looking at
the manual to understand the leading greater than sign mystery, I found
out about background editing, and I think that'd be great for me to be
able to do.

If I understand correctly, I allows you to compose email in an editor on
another tmux window (or screen or graphical editor, but I don't use
those), forking it out of Mutt.  I guess that Mutt would then be free to
use to, for example, check another email, while still composing in the
forked window, or maybe even start composing a new email on a third
window?

That'd be very convenient.  At the moment, when I need to check another
email while composing one, I open a new tmux window and run a new
instance of Mutt, which is OK, but the background editing would be a
marvelous improvement.

I've tried it out with the bgedit-screen-tmux.sh script, but it fails.
I think the problem is that the Mutt version I'm running is a bit old
(1.10.1).  Also, in my .muttrc file I have a comment saying that in
order for folder-hook to work, I needed to upgrade to, at least, version
1.8.0 or later.  By the time I wanted to use folder-hook I tried to
compile Mutt myself, since I couldn't find neither a Devuan/Debian
package nor a pre-compiled generic binary I could use, but I failed.

I settled to wait for a new version of Devuan which would packaged a
newer version of Mutt, and just added the comment as a reminder to
myself for the future.  But, if background editing works as I think I've
understood (as I said before), I think it's really time for me to try
(and succeed this time) to upgrade to a more recent version, because
background editing would really make a big difference for me.

So, my question is: have I understood background editing properly and
will it work as I tried to describe above?  If so, is there any
pre-compiled binary I could use before trying to compile it myself?

Thank you in advance!

Cheer,
Ángel
