How is the «shortcut_buttons_container» event triggered and handled?

It is triggered in the 2 places:

1. Magento\Catalog\Block\ShortcutButtons::_beforeToHtml()

magento/magento2/blob/c3040d36/app/code/Magento/Catalog/Block/ShortcutButtons.php#L66-L81


/**
 * Dispatch shortcuts container event
 * @return $this
 */
protected function _beforeToHtml()
{
    $this->_eventManager->dispatch(
        'shortcut_buttons_container',
        [
            'container' => $this,
            'is_catalog_product' => $this->_isCatalogProduct,
            'or_position' => $this->_orPosition
        ]
    );
    return $this;
}

2. Magento\Checkout\Block\QuoteShortcutButtons::_beforeToHtml()

github.com

magento/magento2/blob/c3040d36/app/code/Magento/Checkout/Block/QuoteShortcutButtons.php#L32-L49


/**
 * Dispatch shortcuts container event
 *
 * @return $this
 */
protected function _beforeToHtml()
{
    $this->_eventManager->dispatch(
        'shortcut_buttons_container',
        [
            'container' => $this,
            'is_catalog_product' => $this->_isCatalogProduct,
            'or_position' => $this->_orPosition,
            'checkout_session' => $this->_checkoutSession
        ]
    );
    return $this;
}

The event is used for adding some extra buttons below the «Proceed to Checkout» / «Go to Checkout» button.
