How do I sync the Solution Explorer with the current File in Visual Studio?

Tools - Options - Projects and Solutions - General - Track Active Item In Solution Explorer

I don't have full Visual Studio, only the Express Editions, where it seems to be checked by default for VB.NET and unchecked by default in C++.NET.

I prefer using the Solution Explorer Tools extension. It allows me to work most of the time without syncying code with solution explorer. when I want to sync I just press the sync button on the solution explorer. It can be downloaded here.

"CTL + '[', S" will synchronize the solution explorer with the file in the current edit window.
