If i have the following
#region
blah;
blahblah;
.....
moar;
#endregion
how can i jump to the top #region label if i see the #endregion tag
I don't believe there's a standard shortcut in Visual Studio.
Within Visual Studio's options dialog, I did a search through all available commands for anything containing the word "region":

But didn't find anything related to navigation, just expand/collapse.
Addins like Resharper and CodeRush may give you what you want, if you have the budget for it. (And they do a lot more besides.)
