    To prompt the user for input, the UIManager class provides a large number of ready to use dialog boxes. For instance, the request:initialAnswer: method returns the string entered by the user (Figure \(\PageIndex{1}\)).

    UIManager default request: 'What''s your name?' initialAnswer: 'no name'

    To display a popup menu, use one of the various chooseFrom: methods (Figure \(\PageIndex{2}\)):

    UIManager default
    chooseFrom: #('circle' 'oval' 'square' 'rectangle' 'triangle')
    lines: #(2 4) message: 'Choose a shape'

    Browse the UIManager class and try out some of the interaction methods offered.
