Thanks.

It's also the main node you get to from `i menu'.  There's
nothing wrong with cross-referencing some "advanced"
information from a "tour" node, as long as it is identified
as such.

I also mentioned an xref in the other direction.  Link to
general info about the menu and using `m', from the node
about using 1-9.

Because it is not how nth is written in English.  Or in
Emacs, for that matter.

OK.  They are menu items, or menu-item descriptions.

How is it consistent regarding these menu items/descriptions?
Some of them use title case and some use sentence case - in
the same menu.

Anyway, if you took care of #1 then thank you for that.
