PowerPoint makes the object you chose the animation’s trigger. You can tell an
animation has a trigger because its number changes to a lightning-bolt icon.
To test the animation, switch to Reading or Slide Show view. When you point at the
trigger, the mouse pointer becomes a hand. Click to see if the animation does what
you want it to.
Tip: Here’s an impressive effect: Use a bookmark in a media file—a video or audio clip—to trigger an
animation. First add a bookmark to the media clip (page 634 tells you how to do that). Then select the
animated object that the bookmark will trigger. Select Animations➝Trigger➝On Bookmark (Alt, A, AT, B).
A menu opens listing bookmarks in the media clip. Select the one you want as a trigger. During playback,
when the clip reaches the bookmark, it starts the animation. Kind of like the “Pow!” “Bam!” “Biff!” that
zoomed in during fights in the old Batman TV show.
Normally, the way you start an animation is to click the mouse. If you’ve got multiple
animations, the first one happens with the first mouse click, the second one happens
with the second mouse click, and so on. And that works fine for many purposes.
But sometimes you want more complex animation. Maybe you’d like to see the title
fly in from the top at the same time a picture flies in from the bottom. Or you’d like
to have a picture of a customer appear, followed a second later by a thought bubble.
You can achieve these and other effects by setting your animations’ timing. You do
this in the Animations tab’s Timing section, using these options:
• Start (Alt, A, T). Use this drop-down list to choose when you want the
animation to start:
— On Click. This is the default option. The animation waits until you click
— With Previous. When you choose this option, the animation happens
concurrently with the previous animation, no mouse click needed. If the
animation is the first one on the slide, it happens automatically when the slide
— After Previous. This option automatically starts the animation after the
previous animation has occurred. How long after depends on the Delay setting.
• Duration (Alt, A, DU). Use this setting to speed up or slow down an
animation. Choose a number, in seconds, to specify how long the animation lasts. So
for an image that fades in, for example, a duration of 00.50 means that it takes
half a second for the image to fully appear. A duration of 01.00 means a slower
fade-in, taking a full second.
