I'm familiar with custom animations and

with previous
after previous
on mouseclick

I'd like to time several animations on a slide to go with narration audio
which is embedded in the slide as an audio object.

One way to do this would be to repeatedly adjust the delays on the
individual objects until the delays match the narration.  Tedious.

I've seen add-in products which provide another method.  Assign mouse-click
to the animations, then play the narration, clicking the mouse at the
appropriate times.  The click events are changed to the appropriate delays
for you.

Where can I find this capability?  (I'm running Office 2007).

Thanks,

KC
