Part 1 is here.
[AF area selection method]
[Orientation linked AF point]
[Manul AF pt. selec. pattern]
[AF point display during focus]
[VF display illumination]
This is the one I was looking for, which is [AF Microadjustment]
This time I pressed [2.Adjust by lens] ten to see what it looks like.
This function is dramatically different form its function of EOS 50D. We are able to microadjust on both side, Wide and Tele. :)
This is an extra information, [C.Fn III: Operation/Others] [Custom Controls]
