In GNU Emacs -Q, `C-h C-f' is `view-emacs-FAQ'. Gnu Emacs has no command
`Info-elisp-ref'. That's XEmacs, and it apparently looks only in the Elisp
GNU Emacs has `Info-goto-emacs-command-node', which is bound to `C-h F'. But it
looks only in the Emacs manual, and it looks only for commands. (There is also
`Info-goto-emacs-key-command-node' (`C-h K'), which looks up a key in the Emacs
What I'm talking about can cover anything you want - by default: functions,
variables, keymaps, modes, faces, and packages.
Anyway, as you say:
> Links are more discoverable
Discoverable? Well, that's one way of putting it! If you're _looking_ at a
link there's not a whole lot of "discovery" needed. (And if you're not looking
at it then good luck discovering it!) But whatever.

Why don't you look at the thread I cited, or even at the patches?
There is only one link (or none, if the user so chooses) - hardly in-your-face.
Clicking it takes you to a virtual Info index of links to the relevant manual
And not just one manual, but a user-configurable list of manuals (by default:
Emacs and Elisp). It works for the Org Mode manual and the Gnus manual and the
Semantic manual and the Widget manual and ... whatever manuals you want.
It is likewise a user choice whether to check the manuals ahead of time (so not
show any link if there is no manual coverage) or to check them only if you click
the link (costs nothing until you click).

No. TAB RET works just as well for following links. Links are not just for
mice. (Nothing new.)

I suggest you read the thread. Only one link is added:
For more information check the _manuals_.
where _manuals_ is a link to an Info index for the sought thingie. That index
lists manuals and nodes, with links.
