react-dnd-accessible-backend/dist/util/isKeyboardDragTrigger.js

An add-on backend for react-dnd that provides support for keyboards and screenreaders by default.

export default function isKeyboardDragTrigger(event, withUntrusted = false) {
    // VERY HACK(faulty): react-dnd-multi-backend fires a "cloned event" after
    // transitioning backends. But, that event is only a base Event, not a specialized
    // KeyboardEvent or MouseEvent, so it doesn't have any of the `.key`, `.metaKey`,
    // etc. properties on it. Because of that, knowing that this is a trigger can
    // only be done by looking at the `isTrusted` property, which is false for
    // custom-constructed events. Eventually, rdmb should fire an appropriate event instead.
    if (withUntrusted && event.isTrusted === false)
        return true;
    return event.key?.toLowerCase() === "d" && (event.metaKey || event.ctrlKey) && !event.altKey;
}
