Either do that, or

    C-u C-h S emacs-lisp-mode RET mapconcat RET

If you (the OP) do this several times a day, you can
do something like this and bind it to a shortcut:

    (defun info-lookup-elisp-symbol (symbol)
      (interactive "Ssymbol: ")
      (info-lookup-symbol symbol 'emacs-lisp-mode))

It can be polished even further with a default to the
symbol at point, however it is only educative to have
to spell out the whole function name when you look
it up.
