In user interface design, a menu is a list of options or commands presented to the user of a computer or embedded system. A menu may either be a system's entire user interface, or only part of a more complex one.
In computer menu functions or buttons, an appended ellipsis ("…") means that upon selection, another dialog will follow, where the user can or must make a choice. If the ellipse is missing, the function will be executed upon selection.
Displays with touchscreen functionality, e.g. modern cameras and printers, also have menus: these are not drop-down menus but buttons.
