Everything is in your manual. On your dial, there are different settings Auto, P, S, A, M

its one of those settings.

I suggest you look at the manual, because everything is explained.

Hey Normally You Got Into A Setting And Then Change Te Shutter Speed using The UP AND DOWN Keys, But Read This Page; It Might Have It IN Here. And Also try reading Your Manual.

I just got my Nikon D3100 today! The way you change the shutter speed is by rotating the mode dial to "S" and rotating the command dial to adjust. Hope this helped!
