Force twittering-mode links to always open in a specific frame?

Question

My (simplified) setup: one frame for twittering-mode and another for w3m, among others, all inside tmux.

While in the twittering-mode frame, C-m on a link does one of two things. Sometimes, the link loads in the w3m frame. Other times, the twittering-mode frame switches to a w3m buffer, so I have to type C-x b C-m to return to twittering-mode after each link I open.

Is there any way to guarantee that the first behavior occurs? It makes browsing Twitter for articles to read very convenient. (Load several, read one, type B to read another.)

I have tried playing with display-buffer-alist, as suggested here, here, and here, all to no avail.

((".w3m.*"
  (display-buffer-reuse-window)
  (reusable-frames . "visible")))

Is this not possible?

Answer 1

The hacky solution is two parts.

First, add this somewhere that'll be evaluated:

(add-to-list display-buffer-alist
    (".w3m.*" (display-buffer-in-previous-window)
              (inhibit-same-window . t)
              (reusable-windows . t)))

Second, make sure that no *w3m<#>* buffers have been seen in your current frame.

(frame-parameters (selected-frame))

...if you see a w3m buffer in buffer-list, you will need to open a new frame.

As long as you never use your twittering-mode frame to visit a w3m buffer, C-m on a link will always load in a separate frame.
