Two possible choices. Apply an animation scheme. In the slide design
animation scheme task pane, choose between a subtle, moderate or exiting
scheme, hit the button apply to all at the bottom of the task pane. That
will take care of slides with titles and bullets.
Second, apply your animation in the master of the presentation. View -
Master - Slide master - select the placeholders you want to animate and
apply a custom animation to it using the custom animation task pane. Be
aware that only object added through the placeholders will be animated, text
boxes or images you insert yourself will not.
