            { "slide": 2, "duration":5000 },
            { "slide": 1, "duration":5000 },
            { "slide": 3, "duration":5000 },
    ];

We are using step number and duration between each step transition in the given array. Only a few astute readers will notice that the step numbers are not in order. That means we can use any step number at any given time making the automation bidirectional instead of forwards or backwards.
