Could you give me some details to which browser and OS you're using? Because those keys do work (Chrome, Firefox, Opera on Windows or Linux)... :/ Maybe if you're using IE/Edge or Safari (or Mac in general) there may be issues as those are relatively difficult to support, and difficult for me to test personally.
