Use the Open Browser Window behavior to open a page in a new window. You can specify the properties of the new window, including its size, attributes (whether it is resizable, has a menu bar, and so on), and name. For example, you can use this behavior to open a larger image in a separate window when the visitor clicks a thumbnail image; with this behavior, you can make the new window the exact size of the image.
If you specify no attributes for the window, it opens at the size and with the attributes of the window from which it was opened. Specifying any attribute for the window automatically turns off all other attributes that are not explicitly turned on. For example, if you set no attributes for the window, it might open at 1024 x 768 pixels and have a navigation bar (showing the Back, Forward, Home and Reload buttons), location toolbar (showing the URL), status bar (showing status messages, at the bottom), and menu bar (showing File, Edit, View and other menus). If you explicitly set the width to 640 and the height to 480 and set no other attributes, the window opens at 640 x 480 pixels, without toolbars.
