Yes. But not with an active mode-line button. That was really my point (and I
should have expressed that more clearly).

I have known, since day one, in case you didn't know.

It is still not something that needs encouraging via a button in the mode line.

I agree that it is helpful to have `Narrow' in the mode line, to let users know
what they're seeing. What I disagree with is that `Narrow' should be an active
button (for Info).

Anyone needing to widen the Info buffer will know enough to do that - s?he won't
need a button for that.

It is the presence of a button that is confusing to non-veterans and encourages
them to get themselves into trouble or more confusion.

There is a reason that `Info-enable-edit' is nil by default. That same reason
supports not having `Narrow' be an active button - at the very least whenever
`Info-enable-edit' is nil.

And I suggest disabling the `Narrow' button, at least when `Info-enable-edit' is
nil. That button is NOT a veteran feature (from day one), and it is not
something that veterans need, in any case.

Try to imagine that you are a newbie and you click mouse-2 on `Narrow'. In Info
that is particularly disconcerting: you are likely to be _very_ confused by what
you see. There is no need for this feature (button) - for newbies or veterans.


BTW, when Info edit is turned on, mouse-1 on `Info Edit' in the mode line brings
up an `Edit' menu. The most important operation is missing from that menu:
`Info-cease-edit' (C-c C-c).
