If you press F3, or the shift key and F3 at the same time to make the meter in the bottom hidden. The "x", "y", and "z" numbers on the left middle side of the screen are the coordinates. X and Z are your north, south, east, and west coordinates, and Y is your current level, Y level 64 being the sea level. If you go below Y level 62, the sky may become darker.
you cant it is only there for show not for anything
you must change the setting so you have to press fn with the F1,2,3... for it to work. Now if you press F5 by itself it will show your coordinates.
If you have gotten latest updates then the coordinates should be at the top left of the map when you look at it.
I dont know
You can either create a map or press F3. Pressing F3 will show you your coordinates, the biome you're in, and a whole lot more.
You cant but, you can look at a map to estimate the coordinates!
Because you have a really bad computer and minecraft is using all of the memory.
There is no other way.
