Ive read several places that suggest how to do it, but right clicking doesnt seem to give me the menus

I have a start screen for the beginning of the stream and I just want to add a simple 5 minute countdown timer on the screen that I can activate
and at the same time play a simple music interlude in the back ground.

Not sure how to do it, nothing Ive read seems to have the options.

Not good a scripting yet.


thanks
