Re: Info tutorial is out of date

    Interesting (and I do the same). Nothing wrong with this use pattern, but I
    wonder if a command that tells you where are (in the manual hierarchy)
    wouldn't be useful. It could be bound, for example, to `.' (a la `pwd').
    (Yes, I know that `.' is currently a synonym for `b'.) It could display a
    "breadcrumbs" message such as this: (emacs) Top > Minibuffer > Completion >
    Completion Commands.

It does sound useful.  In theory, this question does not always have a
well-defined answer, since Info files need not be a tree structure.
But in practice they all are, so there is a well-defined answer.  So
the command would be useful, but it needs to cope in some fashion with
the weird cases.

If someone wants to implement this and contribute it, it will be welcome.
