I know you can find direction using blocks that always have the same orientation (ie crafting tables will always have the sides with two tools on the texture facing north and west, and the sides with a single tool facing south and east), but is there any way to find coordinates without using the F3 screen?

I like playing with reduced debug info and not using the F3 screen since it feels cheaty, but there are some farm designs that simply require exact coordinates. I just want to know if there’s a “legit” way of doing it.
