    if (event.type() == EventTypeNames::keydown)
        type = KeyDown;
    else if (event.type() == EventTypeNames::keyup)

    else
        return; // Skip all other keyboard events.

    modifiers = getWebInputModifiers(event);

        modifiers |= WebInputEvent::IsLeft;
    else if (event.location() == KeyboardEvent::DOM_KEY_LOCATION_RIGHT)
        modifiers |= WebInputEvent::IsRight;

    timeStampSeconds = event.timeStamp() / millisPerSecond;
    windowsKeyCode = event.keyCode();

    // The platform keyevent does not exist if the event was created using
    // initKeyboardEvent.
    if (!event.keyEvent())

    nativeKeyCode = event.keyEvent()->nativeVirtualKeyCode();
    unsigned numberOfCharacters = std::min(event.keyEvent()->text().length(), static_cast<unsigned>(textLengthCap));
    for (unsigned i = 0; i < numberOfCharacters; ++i) {
