A Quick Order block will be displayed in left and right sidebar. This block will also be displayed in shopping cart page. This block contains two fields. One for adding product SKU and the other for adding your desired quantity.
By default, the Quick Order block is displayed in all three positions (Left Sidebar, Right Sidebar, and Shopping Cart Page). You can manage the display of this block from System -> Configuration -> Catalog -> Quick Order.
