Question

I found this nifty little function for Org-mode:

;;; Move to next heading with dedicated buffer preview
(defun ded/org-show-next-heading-tidily ()
  "Show next entry, keeping other entries closed."
  (if (save-excursion (end-of-line) (outline-invisible-p))
      (progn (org-show-entry) (show-children))
    (outline-next-heading)
    (unless (and (bolp) (org-on-heading-p))
      (org-up-heading-safe)
      (hide-subtree)
      (error "Boundary reached"))
    (org-overview)
    (org-reveal t)
    (org-show-entry)
    (show-children)))

It moves from headline to headline, and shows its direct content and children.
I liked the idea, but would rather it would show in a dedicated buffer, using (org-tree-to-indirect-buffer).

I tried to do it like so:

(defun ded/org-show-next-heading-test ()
  "Show next entry, keeping other entries closed."
  (if (save-excursion (end-of-line) (outline-invisible-p))
      (progn (org-show-entry) (org-tree-to-indirect-buffer))
    (outline-next-heading)
    (unless (and (bolp) (org-on-heading-p))
      (org-up-heading-safe)
      (hide-subtree)
      (error "Boundary reached"))
    (org-overview)
    (org-reveal t)
    (org-tree-to-indirect-buffer)
    (show-children)))

But then I have to double press the key – once it shows the entry in a dedicated buffer and secondly it still shows the entry.
I tried to remove the progn function, but then it didn’t work entirely.

I’m not a lisp programmer, and I tried to play with it for an hour or so but to no avail, so I would love someone with some experience to help me sort this thing 🙂

Much obliged.

I ended up making my own, simple functions to navigate more easily:

(defun forward-and-preview ()
    "Go to same level next heading and show preview in dedicated buffer"
    (hide-subtree)
    (org-speed-move-safe (quote outline-next-visible-heading))
    (show-children)
    (org-tree-to-indirect-buffer)
    )
(defun back-and-preview ()
    "Go to same level previous heading and show preview in dedicated buffer"
    (hide-subtree)
    (org-speed-move-safe (quote outline-previous-visible-heading))
    (show-children)
    (org-tree-to-indirect-buffer)
    )
(defun up-back-and-preview ()
    "Go to previous level heading and show preview in dedicated buffer"
    (org-speed-move-safe (quote outline-up-heading))
    (org-tree-to-indirect-buffer)
    (hide-subtree)
    )
(defun up-forward-and-preview ()
    "Go to previous level next heading and show preview in dedicated buffer"
    (org-speed-move-safe (quote outline-up-heading))
    (hide-subtree)
    (org-speed-move-safe (quote outline-next-visible-heading))
    (org-tree-to-indirect-buffer)
    )
(defun inside-and-preview ()
    "Go to next level heading and show preview in dedicated buffer"
    (org-speed-move-safe (quote outline-next-visible-heading))
    (show-children)
    (org-tree-to-indirect-buffer)
    )
(add-to-list 'org-speed-commands-user '("l" inside-and-preview))
(add-to-list 'org-speed-commands-user '("j" forward-and-preview))
(add-to-list 'org-speed-commands-user '("k" back-and-preview))
(add-to-list 'org-speed-commands-user '("J" up-forward-and-preview))
(add-to-list 'org-speed-commands-user '("K" up-back-and-preview))
