But "auto" is not a zoom state at all.
I don't see how it fits in with n/p.

Gnuplot keeps no history of previous plots.
Once you say "set xr [1:10]; plot", that's it, boom, all the
previous states are gone.
The [1:50] resulting plot is not there any more;
the autoscaled resulting plot is not there any more either.
All that n/p/u can do is work with the base state of the
current plot.

Um. Are you sure that's what it currently does?
The sequence of commands you give above does not
act that way when I try it here.
I don't recall ever seeing anything like you describe.

It's clearer in the sense that you really do want a scaling history.
But the program doesn't currently keep anything of the sort,
so it would be a major change. About the same difficulty as
the recurring request for zoomable multiplots, and for much
the same reason. The necessary information is not available.
