Stepping through Linq statement tips

Question

When I step through code and get to a linq statement, the stepping through process and the lines which are evaluated (and their order) are not the same as the code is written. I know this is to do with commands like yield etc.

My questions are:

1. What do I need to learn to understand why the code is debugged in the way it is (with Linq statements)?
2. What stepping through techniques are there for Linq statements?

Oh, and I use Visual Studio 2010 Ultimate.
