Barcode scanner with "ESC" prefix

I would like to configure my barcode scanner to send the "ESC" character as a prefix to ensure that the search box is selected/focused when scanning a barcode. This works fine when adding products to an order or searching for a product in the "Products" page, however it breaks the ability to use the scanner when adding/editing a product. This is because pressing "ESC" while editing a product closes the editing window.

Could Aronium ignore the "ESC" key when adding/editing a product?
Or alternatively, could focus always be returned to the search box whenever possible, eg after deleting an item or changing a quantity?
