well first you need coordinates and it looks like you have to go there and
use the command pos

{MAYBE you could use the mapgenerator site to find coordinates you
haven't been to; I think that's where I got the mistaken idea the map
automatically displayed cursor coordinates)

this gives you x,y,z coordinates ; great

BUT goto x y z is ACTUALLY goto x z y

even then it borked my height a little

and <I think> you need to exit the console for the teleport to happen

incomprehensible; good luck
(enabling god mode was suggested to avoid falling damage)
