I know lynx doesn't change the current link or page info when you type a
link number.  From what you say, it's implemented like a goto.

When you move the current link with the arrow keys and scroll off the page
the page info changes.  The page and current link are also repositioned when
you do a search command.  Would it be that hard to reposition things when you
type a link number?
I don't think that changes the meaning of the back command -- just the def
of what happens when you type a link number.

If the current implementation makes this a lot of work that's another matter
and I understand..
Just wondering.
