This scenario has help me too understand of a lot of methods. http://greenfootgallery.org/scenarios/12 
private void checkKeys()
    {
        if (Greenfoot.isKeyDown("left") )
        {
            setImage("pengu-left.png");
            moveLeft();
        }
        if (Greenfoot.isKeyDown("right") )
        {
            setImage("pengu-right.png");
            moveRight();
        }
        if (Greenfoot.isKeyDown("space") )
        {
            if (onGround())
                jump();
        }
    }
You can find this code in the Actor Pengu. Have a nice day. Advenging
