A menu is a set of options presented to the user of a computer application to help the user find information or execute a specific program function. Menus are common in graphical user interfaces (GUIs) such as Windows or Mac OS X. Menus are also employed in some speech recognition programs. In a graphical drop-down menu, clicking on an item (text word, button or icon) causes a list of new items to appear below. An example would be clicking on one of the text words such as “File” or “Edit” in the horizontal list at the top of the screen in a Mac or Windows application. Clicking on an item in the menu executes the indicated function, opens a dialog box, or generates another menu.
