Ability to press enter to add lines using multi-line order entry

It would be useful when using the multi-line entry screen in the web UI to be able to choose quantities for all the products you want and then press the enter key on the keyboard to add those products to the quote - this would reduce the time it takes to add lines to a quote

Not sure whether it would be best to have this keyboard shortcut for 'Add' or 'Add and Close'
