By default, when you are in HTML source-editing mode with VS
2008 and Visual Web Developer 2008 Express edition there is a set of drop-downs
that are rendered immediately above the HTML text editor view:
This set of drop-downs is called the "Navigation
Bar", and in the VS 2008 HTML editor they allow you to navigate between
functions and methods defined within the HTML. These include both
JavaScript client-side functions defined inline within the .aspx/.html file, and
server-side methods defined in-line within the .aspx file when in single-file
mode (meaning no code-behind file).
