Then we need a way to keep track of what property keys are used to store outlines in, so we can offer those and only those for completion. (We don't want to offer all the property keys used in the buffer -- that's an invitation to overwrite data.) So in my second pass (below), when you use a :foo: property to store the outline index, `foo' gets added to a list of keys in the :Stored_outlines: property of the parent. When you store an outline, the prompt for a property key offers completion on all the keys stored in :Stored_outlines:. See how this works for you. Yours, Christian #+BEGIN_SRC emacs-lisp (defun cm/org-store-outline-order (arg prop) "Store the heading order of the subtree of the entry at point by setting the property PROP of each direct child entry to its current position in the tree. With prefix ARG, store the position of the whole subtree. You can store different heading orders in the same subtree by using different keys as PROP; these will be listed in the Stored_Outlines property of the parent entry. The tree can be restored to a given stored outline by sorting on the appropriate property with `C-c ^ r'. Note that this will only work properly on the order of each subtree; if headings are demoted, promoted, or moved into different subtrees, the result may or may not be nonsense, but it will be impossible to restore the original order by sorting." (interactive "P\ni") (let* ((match (format "LEVEL%s%s" (if arg ">=" "=") (1+ (org-current-level)))) (counter 1) (width (1+ (floor (log10 (length (org-map-entries t match 'tree)))))) (fstr (concat "%0" (number-to-string width) "d")) (defaultprop "OutlineIndex") (keychain "Stored_Outlines") (keys (org-entry-get-multivalued-property (point) keychain))) (unless prop (setq prop (org-icompleting-read (concat "Property to use [" defaultprop "]: ") (mapcar 'list keys) nil nil nil nil defaultprop))) (when (or (not (org-map-entries t (concat prop "={.}") 'tree)) (y-or-n-p "Property exists; overwrite?
