Thanks for the answer sorry I didn't present the question correctly

No worries at all.  The important part to phrasing the question clearly in the future is getting you a fast response as well as helping others who may experience the same issue find the question.

Consequently, for those reading this, the original question was trying to figure out how get Visual Studio's Solution Explorer to focus on the file one currently is editing.  This was on by default in older versions of VS but is off by default in newer ones --- at least it was for me on VS 2013.
