    Input widget takes one variable path, and displays current value in
    optional "value" labeled sub-element. 

    Click on optional "edit" labeled element opens keypad to edit value.
    
    Operation on current value is performed when click on sub-elements with
    label starting with '=', '+' or '-' sign. Value after sign is used as
    operand.
