如何使Xcode 4.1代码自动完成？

Question

I just bought a MBP and trying out Xcode. I know code completion works fine when pressing 'Escape', but how can it work automatically with Xcode 4.1? For example, pressing down '.' in C++?

I read several posts on this. Some suggest going to preferences and turning it on, but I didn't see any option. Can you please provide a list of steps?
