Define special parameters to control Shockwave and Flash SWF files, ActiveX controls, Netscape Navigator plug‑ins, and Java applets. Parameters are used with the object, embed, and applet tags. Parameters set attributes specific to different types of objects. For example, a Flash object can use a quality parameter <param name="quality" value="best"> for the object tag. The Parameter dialog box is available from the Property inspector. See the documentation for the object you’re using for information on the parameters it requires.
Right-click (Windows) or Control‑click (Macintosh) the object, and select Parameters from the context menu.
Open the Property inspector if it isn’t already open, and click the Parameters button found in the lower half of the Property inspector. (Make sure the Property inspector is expanded.)
