Navigating highlighted identifiers in Visual Studio .NET

This FAQ id about a Visual Studio short cut that allows navigating across highlighted identifiers.

Often in our code, we navigate between multiple occurrences of an identifier. When we place our cursor on one such identifier, Visual Studio automatically highlights all occurrences of it. To navigate to the previous or next occurrence of a highlighted identifier, use CTRL+SHIFT+UP ARROW and CTRL+SHIFT+DOWN ARROW respectively.
