You know those little bitty JavaScript windows? You can pop one open using the Open Browser Window action—or you can pop open a regular-sized window. Incidentally, each of these pop-up windows has a unique URL that belongs to a distinct HTML document that you must create separately.
Usage Example: Pop open a floating toolbar, "control panel," or a window set to the exact size of a Shockwave applet or streaming video ( Figure 16.22 ).
