Hi, I'm sorry that I miss read your question.
No, org-store-link, or org-info-store-link to be precise, doesn't support storing the index you just used or you are on. I'm not sure how to figure out what a user is trying to store is either the current node or the index. You can, however, write a link by hand [[info:elisp#define-minor-mode]] and org is happy to open and jump to the entry pointed by the index. regards, -- yashi
