tell target to main timeline?

I am trying to reference the main timeline from a movie clip . it wont work!!!

Ive seen it done using telltarget "_level10/" but what the hell is that. I am familure with targeting an instance name but what is the underscore?

I know some better men than me can do it. until then it will taunt me until the wee hours of the morning!!

Thanks in advance for any help.

This is the easy way to do it.
This goes in the clip.

tellTarget ("/") {
nextFrame ();
}

is that to say that targeting "/" in place of an instance name will refer to the main timeline?

What is the nextframe() for?

Exuse my ignorance, and thanks for the help.

I'll give this a shot as soon as I get home.

you can control the main timeline as if it were a normal movie clip, nothing different at all. The name of the main timeline is "/" Just think of it as a movie clip, it works.
