Open a footnote definition outside a narrowed subtree (workaround)

[Juan Manuel Macías]

Hi all,

When I am working on a narrowed subtree and want to open a footnote for
editing (`C-c C-o': `org-open-at-point'), I get the message: "Definition
is outside narrowed part of buffer". I don't know if there is a
"standard" solution for that (aside from cloning the buffer and/or
removing the restrictions)... I’ve written this simple and quick
workaround, and then remapped `C-c C-o' so that:

`C-u C-c C-o'
      my function
`C-c C-o'
      `org-open-at-point'

┌────
│ (defun my-org-open-fn-indirect-buffer ()
│   (interactive)
│   (if (not (equal (org-element-type (org-element-context)) 
'footnote-reference))
│       (error "Not in a footnote reference!")
│     (let* ((el (org-element-context))
│            (label (org-element-property :label el))
│            (buf (buffer-name))
│            (format (format "%s | Note %s" buf label)))
│       (when (get-buffer format)
│       (kill-buffer format))
│       (clone-indirect-buffer format t)
│       (setq header-line-format (format "NOTE %s" label))
│       (widen)
│       (org-open-at-point)
│       (recenter 0))))
│ 
│ (defun my-org-open-at-point ()
│   (interactive)
│   (if (equal current-prefix-arg nil)
│       (org-open-at-point)
│     (my-org-open-fn-indirect-buffer)))
│ 
│ (with-eval-after-load 'org
│   (define-key org-mode-map (kbd "C-c C-o") nil)
│   (define-key org-mode-map (kbd "C-c C-o") 'my-org-open-at-point))
