I can't display the chunk borders, even if I hit F3 + G. How do I get them to show up?
I know that sometimes you need to hold down the function key (Fn on most keyboards) for the F keys to work. Try Fn+F3+G.
One of the MC devs (Dinnerbone) has an online tool that allows you to calculate chunks. https://dinnerbone.com/minecraft/tools/coordinates/
On some computers, it is just F3+G but on mine is an HP and I use fn+F3+G
Go into chat settings and disable reduced debug info.
It should re-enable the following:
- Chunk borders
- Bounding boxes
- Block info
- Chunk info.
- Facing info.
- Client and server light info.
- Biome info.
- Sound info.
- Difficulty info.
And probably more.
