How to rotate clockwise in animation 2D

I have a gameObject that i would like to rotate using the graphical animations window. I can only rotate it counterclockwise. How would I change it so that its rotates clockwise instead

Well, if you have the animation clockwise rotation you can do that rotate to the left with the same animation.
in the script you write something.

    public Animator anim;
    void Awake()
        anim = gameObject.GetComponent<Animator>();
    public void accion()
        anim.SetFloat("change",-1);// in the reverse direcion
        anim.SetFloat("change", 1);//to go in the normal direction 
        anim.SetFloat("change", 0);//stop animation

Remember to put in the parameter change 1. that if he was ever stopped.

you decide if the animation will have infinite loop or only once.

and forgive if not what you were looking for.
