JS: "CTR + Wheel" Event

/**
You can change the window to element you want this event to happen.
example: document.getElementById("view-chapter-verse").addEventListener()
*/
window.addEventListener("wheel", function (event) {
        event.preventDefault(); // this will prevent the scaling for browsers.
        if (event.ctrlKey) { // check if we are pressing the CTR key
            if (event.deltaY) {
                // Do what you want here. In this example
                // Im trying to change the Font Size of my article
                // event.deltaY is less than 0 it means we are scrolling up. If not scrolling down.
                fontSize = event.deltaY < 0 ? fontSize.value + 0.5 : fontSize.value - 0.5;
            }
        }
});
