When I use helm-mark-ring or helm-imenu, I would like to jump to the current candidate automatically in the other buffer while keeping the helm session (i.e., similar to helm-swoop). I tried the following codes mentioned on this thread, but didn't work for me.

(add-hook 'helm-before-initialize-hook #'(lambda () (helm-attrset 'follow 1 helm-source-mark-ring)))

Result: It shows [Display not ready] in echo area when I change the helm candidate (by C-n).

Any help appreciated!

Put this in your .emacs (setq helm-follow-mode-persistent t) and whenever you enter helm-imenu or helm-mark-ring, press C-<up> or C-<down> to follow to that line in helm.

  • Thanks for the reply. I added the setq, but the helm session closed when I do C-<up or C-<down>. – AhLeung Aug 15 '16 at 17:44
  • That is strange, it works perfectly fine for me. Can you elaborate on what exactly happens when you press C-<up> or C-<down> ? Have you bound C-<up> or C-<down> to some other command ? And if you still have the add-hook command you mentioned in the post, i.e. `(add-hook 'helm-before-initialize-hook #'(lambda () (helm-attrset 'follow 1 helm-source-mark-ring)))' , please uncomment or remove this line and reload .emacs. – Chakravarthy Raghunandan Aug 15 '16 at 17:51
  • More details: For helm-mark-ring, it jumps to the location correctly, but the session closed when I pressed C-<up> or C-<down>. For helm-imenu, I got the following error when I pressed C-<up> or C-<down>: (wrong-type-argument stringp #<marker at 150961 in work.txt). I removed the hook command, and I didn't redefine the key. I will try emacs -Q later. – AhLeung Aug 15 '16 at 17:51
  • Maybe you have something in your .emacs that is messing things up. Can you think of anything in your .emacs that is messing things up ? If not, edit the post adding the lines in your .emacs used for helm config – Chakravarthy Raghunandan Aug 15 '16 at 17:56
  • You are right! The following code messed up the persistent action: (advice-add 'helm-execute-persistent-action :around #'dwim-helm-find-files-navigate-forward). After removing that, your answer works for me now. Thank you very much! – AhLeung Aug 15 '16 at 18:26
