How to View Flash Layer Objects Using the Preview Modes
Preview mode is used to toggle between a full render preview or a series of bounding boxes. You can toggle individual layers between preview modes or set the preview mode globally.
Open a new document and add a second layer. Name the upper layer Top and the lower one Bottom.
Using the drawing tools, add objects to each of the layers.
Click the preview box for the Top layer to view your shapes in bounding box mode.
Click the preview box a second time an the objects reappear.
Choose View > Preview Mode > Outlines. All objects on both layers are converted to outlines.
Choose View > Preview Mode > Anti-Alias Text. The objects reappear.
