"In computing and telecommunications, a menu or menu bar is graphical control element. It is a list of options or commands presented to an operator by a computer or communications system. ...
A computer using a graphical user interface presents menus with a combination of text and symbols to represent choices. By clicking on one of the symbols or text, the operator is selecting the instruction that the symbol represents. A context menu is a menu in which the choices presented to the operator are automatically modified according to the current context in which the operator is working.
A common use of menus is to provide convenient access to various operations such as saving or opening a file, quitting a program, or manipulating data. Most widget toolkits provide some form of pull-down or pop-up menu. Pull-down menus are the type commonly used in menu bars (usually near the top of a window or screen), which are most often used for performing actions, whereas pop-up (or "fly-out") menus are more likely to be used for setting a value, and might appear anywhere in a window."
