What is the shortcut for opening MSDN page in Visual Studio 2013

Question

I am thinking that there may be some shortcut for opening the related MSDN page for default c# methods classes etc.

Such like:

String variableName = "Variable";

press some shortcut while String focused and it opens: String Documentation

Answer 1

Place the cursor on the keyword and press F1. You will be redirect to related MSDN page. Example in your case

String variableName = "Variable";

Put your cursor on String and press F1 you will be redirected to MSDN page of String documentation.
