The problem is that we're running out of interesting keybindings. "C-c
j" is not an option since it is reserved to users.

Another option would be to add it to Worg.

Note that you can use

  (let ((h (org-find-property "CUSTOM_ID" custom-id)))
    (when h (goto-char h)))

instead of

  (org-link-search ...)

for one less level of indirection.

Indeed. I modified it so it uses `org-find-property'.
