Use commands on the View menu to adjust your view of the Stage.
100% command Sets the zoom level to 100% so that your drawing appears as close as possible to actual size. This is the same as using the zoom controls on the toolbox. (Depending on your monitor and video card, 1 inch on the screen may not equal 1 inch on the Flash rulers.)
Show All Sets the zoom level to display the contents of the current frame. If the scene is empty, the entire scene is displayed.
Show Frame Sets the zoom level to display the entire scene. As a shortcut to this command, double-click the hand tool.
Work Area Makes the work area that surrounds the frame of your movie visible. The work area is shown in light-gray. Use the Work Area command when you need to work with parts of your drawing that are partly or completely out of the scene. For example, to have a bird fly onto the screen, you would initially position the bird off-screen in the work area. To see the most work area and Stage, choose View > Work Area and View > Show All.
