I am using Aquamacs 3.3 GNU Emacs 25.1.1 and Dired+. Sometimes the key sequence C-x C-j opens the Dired buffer in a new frame instead of a new tab in the running frame.

I want the behaviour that the the Dired buffer is opened in a new tab always. What can I do?

  • Did you really mean tab, or did you mean Emacs window? I edited it to say the latter, but please change it back if I was wrong. (You wrote "window" where you apparently meant "frame" - I changed that too.)

  • Perhaps what you see comes from Aquamacs. Dired+ just leaves C-x C-j bound to dired-jump, which does not open either a new frame or a new window.

    FYI -- for anyone who is curious about Aquamacs v. Emacs as to the tabbar library: Aquamacs is distributed with a built-in version of tabbar with some modifications to said library. The generic/vanilla version of Emacs does not ship with Emacs. Here is a link to various tabbar configurations for the generic/vanilla version of Emacs: emacs.stackexchange.com/questions/10081/… The following link to marmalade contains installation instructions: marmalade-repo.org

I found the reason for the behaviour myself. It is not a dired problem. Aquamacs has the Options menu where you can select "Show buffers in new frames" what was set accidentally.
