Office 2003 on WinXP

I have a series of animations on one slide that need to be triggered by me
(one mouseclick per animation). The very last animation is a fade/exit of
one graphic, and what I'd like to do is (at the end of that fade) have the
slide show automatically advance to the next slide, on that slide only.

I have found slide transitions, and if I set it to mouseclick, then I'm
still up there clicking more than once (and having to wait until the end of
the fade/exit animation to do it). If I put it on a timer, it actually
forces all of my other animations to happen in rapid sequence on that slide,
even if I haven't mouseclicked to trigger any of them.

Is there a way to trigger a slide transition at the end of an animation?

Thanks,
Keith
