       Packages:  Look under flash.net Package
                             ---------

      Functions:  Look at the navigateToURL() function documentation.
                              ---------------


                                                 --------------
Note:  Frame #100 would normally have ONLY THESE TWO STATEMENTS!
                                                 --------------
stop();
navigateToURL(link, "_self" );

You almost always want to navigateToURL() to the SAME WEB PAGE whether:

      1.  the user clicks the button to skip the Flashy Flash intro, or

      2.  the entire Flash intro plays and finishes, so that the 
          user is now automatically taken to the web page the
          flash intro was just preparing you and motivating you for.

// Frame #1 has these statements, including declaring the 
//          varIABLE named link.

In summary, 
            var link2:URLRequest = new URLRequest("http://www.uni.edu");

                      is really not needed!!!!!

             Just use the already declared link variable from frame #1!

skip_btn is the INSTANCE NAME of a button.
--------


skipButtonSymbol might be the name of the SYMBOL in the Library.
----------------

You cannot give anything an instance name when you are creating it as a 
symbol or when you are converting it to a symbol (Button or Movie Clip 
type symbol).

You can only give something an INSTANCE NAME when it is on the stage!!!

------------------------------------------------------------------------
CHAPTER 07 of the textbook explains all of this in much more detail and 
  walks you through an example, so be sure to read and perhaps to DO 
  that example to get the foundation for doing Flash intros.
