<P> The highlighted orange keys show the accents available from the combination of the Alt key and the keyboard characters e i u (on the top letters row) and ` n (on the bottom letters row). The accent then can be applied to associated letters both lower and uppercase . The additional characters a Mac will produce are a combination of both the ⌥ Option key and the ⇧ Shift key pressed down together . With this combination pressed the keyboard will now produce a different set or an uppercase version of the previous set in some cases . </P> <P> When a user presses the Alt key by itself on Microsoft Windows, that moves keyboard focus to the menubar of the application having keyboard focus, and the key is not delivered to the application . In that state, another press of the Alt key will be delivered to the application . </P> <P> On other platforms, for example Ubuntu, the Alt key pressed by itself may invoke another application and not be delivered to the application having keyboard focus . In Ubuntu 16.04, pressing the key opens the HUD, which is an input field that lets you do menu commands such as opening a file, or creating a new file . </P>
