Sadly we don't support this feature at the moment - one of those things that keeps on getting mentioned but never actually implemented.  Definitely should be on the list for a future release though.  Probably in COBOL terms the syntax would be:

     $region "Tab1_Instruction"

Perhaps worth mentioning that we do have automatic outlining in Visual Studio. New sections or methods will have a collapsible outline created as you type your code.

You might be interested in the *>> support - type this at the top of a method with the * starting in col 7 to generate intellisense documentation.

As Robert mentions, region support is something we've looked into before. Community postings like this one will help us prioritise these features for a future release.
