Full screen with key input
For security reasons, most keyboard inputs have been blocked in the fullscreen mode. However, in Google Chrome you can request keyboard support by calling the method with a flag:
docElm.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);This does not work in Safari, and the method won’t be called.
With Firefox, we are discussing and looking into various ways of how we we could add keyboard input support without jeopardizing the end user’s security. One suggestion, that no one has implemented yet, is the requestFullscreenWithKeys method, which in turn would trigger certain notifications for the user.
