Flash KeyNav through Array of Functions

programming flash
1

I’m basically creating a glorified Powerpoint presentation… except a lot more “flashy”.
If there is a better way to do this, just tell me.

I have each “slide” basically as a function of animations (done with greensock tweenlite).

I want to be able to go to the next slide (function) in the list by pressing the right arrow key.
And back with the left key, etc…

Some things i’ve looked at but not quite got it…

Everything i’ve tried to make keeps breaking.
Forgive my non flash eliteness.

If you have more questions, hopefully i have answers!

The code that i do have… but like i said i need it to go to the next function (in an array i guess).

stage.addEventListener(KeyboardEvent.KEY_DOWN, keycontrol);

function keycontrol(event:KeyboardEvent):void
    {
    switch (event.keyCode)
        {
        case Keyboard.LEFT:
        {
            objectives();
        }
        case Keyboard.RIGHT:
        {
            objectives();
        }
    }
}
