Rmail: toggle between summary and message buffers

Rmail: toggle between summary and message buffers

[Xavier Maillard]

Hello,

since quite recently, I would have used only the Rmail message
buffer. Then I discovered C-M-h aka `rmail-summary' which is quite
convenient.  There is something quite annoying though, I do not know
how to switch from rmail-summary's buffer and rmail buffer.

I have read the manual and info pages but I am pretty sure there is no
pretty simple way to do so. WHy I would like to have this ? Simply,
sometimes, I have to activate a link from the rmail message buffer or,
I need to copy something from it, etc.

If nothing exists, I would report it as a bug so we can have it but,
before that, is there something I could try ?

Thank you

I don't understand the question.  Both Rmail buffer and Rmail Summary
buffer are just buffers, so you switch between then just like between
any other two buffers.  What am I missing?

Maybe I am not clear (english is not my native tongue, sorry).

So, I need a quick, direct and easy way to switch from a message
buffer to the rmail-summary buffer and vice-versa.

Currently, I am doing a lot of `C-x o' but as soon as there is more
than one window, this is getting quite useless.

I haven’t ever used rmail, but Gnus has a pair of functions
gnus-summary-select-article-buffer and gnus-article-show-summary, bound
to h in gnus-summary-mode-map and gnus-article-mode-map respectively,
which allow conveniently switching between the summary buffer and the
message buffer.

I think Xavier is looking for a similar pair of functions for rmail, as
opposed to having to use the general other-window bound to C-x o.

Exactly this, yeah. Here `h' activates the rmail-summary function
(removing any applied filters if any in action) which is kind of
disturbing.

When I use Rmail I only have the rmail buffer and the summary buffer
open.  I don't have any more windows in that frame.  I also bind a
shorter keybinding to other-window.

I know that this is not really a solution, but it may help.

BTW, you have get the summary buffer with just 'h' by itself you don't
need 'C-M-h'.

Exactly my case: two windows, the summary at the top, the Rmail buffer
at the bottom, and a single key to switch.

So there is something odd here. I will track it and fix it.

First thing first, getting rid of the BBDB popup I installed (I thought it would be useful but it is not).

Thank you for reporting back.

That's not the case here. Worse, when I send an email (C-c C-c), I am not returning back to my rmail window, it just randomly goes back the scratch buffer.

What do you use instead of C-o ?

There is something wrong here, so, yeah, that helps.

Yeah, I know. I am just used to using C-M-h :)

FWIW, I bind "M-o" to other-window globally, and think it's the most
useful re-binding I've ever done. I've never missed the font thing that
was originally bound there, I don't really know what it did.

I use M-HOME and M-END, with this piece of code:

  (defun my-previous-window (arg)
    "Switch to previous window."
    (interactive "p")
    (other-window (- arg)))
  (global-set-key [M-home] 'my-previous-window)
  (global-set-key [M-end] 'other-window)

That's good -- I often want to cycle back the other way. [home] and
[end] are in very awkward places on my keyboard, though, maybe M-O...

I am not keen on changing M-o but the idea behind this is cool.

> I use M-HOME and M-END, with this piece of code:

Awesome ! [home] and [end] are not easy to reach on my keyboard.

I am using your code with M-up and M-down. This drastically change
things.

Don't use "C-c C-c".  Use "C-c C-s" instead, and have a separate frame
for the *mail* buffer where you compose and send email.  Then Emacs
will not mess up your windows in the Rmail frame.

Btw, a nice side effect of this arrangement is that the next 'm' or
'r' will reuse the frame showing the *mail* buffer, so just let that
frame hang around, to be used for composing and sending email
throughout the entire session, with no need to switch to any buffer in
your other frames.

I will test this but here it does not seem to select the right frame.
Maybe I misunderstood something.

I think you also need to set rmail-mail-new-frame to a non-nil value.
With that, the first time you reply to an email from Rmail, it will
create a new frame for the outgoing email, if one doesn't already
exist.

You will also need to set message-generate-new-buffers to the value
'standard', so that the name of the buffer where you compose email is
fixed (and thus it could be reused for subsequent email messages).
Alternatively, do this:

  (setq mail-user-agent 'sendmail-user-agent)

which will ensure the outgoing email buffer is always named "*mail*".

Sorry, forgot to tell about all that (this is setup I've done many
years ago).

Perfect. You can forget my previous message. This does exactly what

Do you mean to C-x 5 2 from the *mail* buffer ?

I mean "C-x 5 b *mail* RET" (which should be done only once per Emacs
session), and then use "C-c C-s" to send mail you composed.

Did it here and it effectively create a new frame but when I press 'r'
or 'm' right from the rmail-message buffer, it just splits my current
frame into two windows and it shows me the *mail* buffer right
here. It also displays the *mail* buffer into the separated (and
dedicated frame) though.

I did try it with emacs -q just to be sure I did not something wrong,
same behaviour.

Do you get this too ?

Thanks anyway, going C-c C-s is a neat tip (I must adapt to it now but
it is okay).
