My Instruction Manual shows that there are only 3 options for Selectable AF Point:

0: 19 points
1: Inner 9 points
2: Outer 9 points

However, the camera menu shows 6 options:

0: 19 points
1: Inner 9 points
2: Outer 9 points
3: 19 points (*)
4: Inner 9 points (*)
5: Outer 9 points (*)

Options 3, 4, & 5 show little arrows within a pair of brackets after the word "points". I have no idea what these signify, nor do I know what the difference is between options [0, 1 & 2] and options [3, 4, & 5].

Does anyone know if there is any difference?

It's FW updated function, it means using the JOYSTICK selector to choose AF point manually.

Cheers

Thanks, that was easy.
