I wrote this there: ---- Since 2011 library `help-fns+.el' has had that feature. And it's user configurable - not just on/off, by option `help-cross-reference-manuals': 1. Choose the list of manuals to search. Default: Emacs and Elisp manuals. 2. Choose whether to (a) search systematically, when `*Help*' is created, and add a `manuals' link only if search finds hits, or (b) always create a link, and search only when the link is followed. Default: (b). https://lists.gnu.org/archive/html/emacs-devel/2019-07/msg00242.html This feature is implemented by searching the manuals listed in a user option. By default, the manuals are Emacs and Elisp. But you can choose any Info manuals you like. Now if Emacs itself implemented such a feature then there might presumably be no need to search for the right manual location(s) to visit either (a) when you display the *Help* that contains the link or (b) when you click the link. Emacs itself could perhaps have an internal table that gets populated at build time - at least for manuals such as Emacs and Elisp. And if more manuals were chosen by a user (by such an option) then those additional manuals could be handled similarly to what `help-fns+.el' does now: user choice whether to search (a) when *Help* gets displayed (slow, and useless if there's no match) or (b) only when you click the link for Info. Note that the `help-fns+.el' implementation adds a single link in *Help*. When followed, if there are hits in both Emacs and Elisp then it goes to an Info buffer that has a links to each of those manuals. (If only one manual covers it then the link takes you directly to that location.) https://www.emacswiki.org/emacs/download/help-fns%2b.el
