I just upgraded from Fedora Linux 32 to Fedora 33 and I think this updated emacs as well because I now see some new behaviours. I have set: (global-set-key (kbd "<f6>") 'org-todo-list) so that I can press F6 to open the TODO list and it used to open on the right, which is what I want. Now it opens below. I did some research and found: (setq split-width-threshold 1) Which does open the TODO list on the right. BUT when I middle-click on a TODO item in the list, in order to bring the cursor to my org file, in order to mark a TODO item as DONE, sometimes (this seems like a weird behaviour) emacs will open a new window/frame with the org file to the right of the TODO list. So now I have: | org file | todo list | same org file | side by side. I have been searching for other ways to fix this, but found nothing. Any help is much appreciated.

    It's always good to write alternatives that you tried that can help for others to find some solutions. Beside that can you look for popwin-mode I guess in that way also you can achieve what you want. Commented Apr 20, 2021 at 15:18

1 Answer 1


I found using a higher value, eg (setq split-width-threshold 100) resolved the issue.
