Accessing Lisp Intro with eintr

[Heime]

Using info, this is the way to access the manuals using "elisp" and "emacs".

C-h i m elisp <Ret>
Visits the Emacs Lisp Manual.

C-h i m emacs <Ret> Visits the Emacs Manual.

But the above does not work quite well with the Introduction to Emacs Lisp 
manual, because
I cannot do

C-h i m eintr <Ret>

Rather, one has to do the following, with spaces etc.

C-h i m emacs Lisp Intro <Ret>

Would be grateful if info could access the intro with

C-h i m eintr <Ret>
