Stupid basic question

Hello people. I can beleive after 5 years with flash I cannot do this:

How do I jump to a particular frame in a particular movieclip from another movieclip?
The two movieclips are in the main timeline.
When I run the movie, it goes to frame number one which has two buttons: English and Spanish. The button takes you to frame two if you ckick on “english” and frame 3 if you click on “spanish”. These frames contain the spanish_mc and english_mc, depending the button you click on. Each of these movieclips has an animation to be shown after you selected the language. So far so good. After the animation you’ll see the menu screen for that particular language but also it will be a button to jump to the main menu on the other language, without going thru the animation for that language.

This is, to make long story short: I need to be able to jump from the main menu on the spanish MC to the main menu on the English MC, without going thru all the frames again. How do I do that?
