If you want to keep an objects timeline attributes such as entry and exit points but want to shift the whole timeline so that it appears at a different time during the slide's duration you can shift the object's timeline. Press and hold the mouse button. Drag the timeline to it's new location. Release the mouse button. Transitions and Path Animation Transitions are special effects that can be added to objects on slides or slides themselves.
Transitions consist of dissolves, fades, and wipes.
You can also make objects move on your slides by using path animation. You simply define where an object comes on to the screen, the path it takes to move across the screen, and where it exits the screen. When you add a transition to a slide it appears at the beginning of a slide, therefore if you want the transition to appear between the first and second slides in a presentation you should place it on the second slide. Choose a transition from the Slide Transitions dialog box. To Time box.
