I don't remember checking "Ping" but it's checked when I go to edit the
scan. I assumed that "Ping" meant "ICMP Echo" corresponding to -PE. But
instead it means -sn.

I don't think of -sn (aka -sP) as "ping scan" anymore, but as "skip port
scan." That's why the option name got changed, because you can get more
than just ping with -sn (NSE, traceroute).

I expected the checkbox controlling -sn to be under "Look for open
ports," not "Check responsiveness," because that's the phase it belongs
to. Just like -Pn is at the top of "Check responsiveness," to me it
makes sense for -sn to be at the top of "Look for open ports."

Under "Check responsiveness," if I only check
* Skip discovery / assume online
it gives me the command

# nmap -sU -sV -p 5350,5351 -T3 -v -Pn -PE -PP

The -PE and -PP override the -Pn and I don't get any results because the
host is found down.
