pointer to start video and/or music

[wabash12]

Have a PPT with a music and videos on different slides that I start with a mouse click after advancing to the slide using custom action button or the sound icon.
What I'd like to do is somehow start the music/vidoes after the slide is showing but with the pointer. Now when I forward(click) with the pointer it goes to next slide. The only way I've somewhat figured it out is to create a blank 'holding' slide then click to slide and auto start music.



any help/suggestions please,
