To set properties and parameters for individual screens, use the Property inspector. On the left side of the Property inspector, you can view the instance name, width, height, and x and y coordinates of a screen.

• The instance name is a unique name assigned to a screen, used when you target the screen in ActionScript. Each screen is assigned a default instance name, based on its default name in the Screen Outline pane. The instance name and default screen name are also identical to the linkage identifier for the screen. If you update the instance name, the default screen name and the linkage identifier are also updated.

• Width and height are specified in pixels. The values in the W and H fields are read-only. Width and height are determined by the screen contents. To make sure the registration point stays in the same relative position when the screen width and height change, use the Auto Snap option.

• The x and y coordinates of a screen are specified in pixels. Move a child screen on the Stage by changing its x and y coordinates. Change the registration point of a screen using the registration grid.

  To control screen behavior during playback, set parameters for slide and form screens.
