Selecting a focus point on Nikon D3100?

I already know how to change the AF modes to AF-A, AF-S, AF-C, MF. But when I put it on AF-S I don't know how to select one of the 11 points; its always on the right side. I also already tried reading the manual but couldn't find it… Please help

In AF-S, you should be able to just move it around with the multi-selector control.
