You can add behaviors to your page to start and stop various media objects.
Control Shockwave or Flash lets you play, stop, rewind, or go to a frame in a Shockwave movie or Flash SWF file (see Control Shockwave or Flash).
Play Sound lets you play a sound; for example, you can play a sound effect whenever the user moves the mouse pointer over a link (see Play Sound).
Check Plugin lets you check to see if visitors to your site have the required plug-in installed, then route them to different URLs, depending on whether they have the right plug-in. This only applies to Netscape Navigator plug-ins, as the Check Plugin behavior does not check for ActiveX controls. For more information, see Check Plugin.
