Visual Studio .NET 2005 - Code Snippets Demo

The above Code snippets demostrates the following snippet types

• Simple expansion
• Template expansion (with variables)
• Surround
  

Open the snippet manager
Ctrl+K, Ctrl+B

To activate a snippet ... start typing the name of the snippet
Tab,Tab (in C#)
?,Tab (in VB.NET)

.. and the snippet will appear. If it's a templated snippet:
Tab advances to the next field
Shift+Tab moves to the previous field
Enter completes the snippet and resumes editing at your previous cursor position

If you want to enclose code in a surrounding snippet (eg, you have code highlighted for a region), you must manually invoke snippet intellisense by pressing: Ctrl+K, Ctrl+X
