Fnd_Nav_AddButtonMethod

            Fnd_Nav_AddButtonMethod (method; label{; foreground color; background color}})

              Parameter                 Type             Description
              method                    Text             Method name to execute
              label                     Text             Button label
              foreground color          Longint          Text color (optional)
              background color          Longint          Background color (optional)

            This routine adds a new button to the palette and assigns the method as its action. When the button is
            clicked, the first parameter, method, will be executed.
              Fnd_Nav_AddButtonMethod ("MyCoolMethod"; "Run Cool Method")

            You can include parameters or any other executable code as the first parameter. For example, the
            following example will pass a text and a numeric parameter to MyCoolMethod:
              Fnd_Nav_AddButtonMethod ("MyCoolMethod("\one\";2)"; "Run Cool Method")

            If a button with an identical label already exists, it is updated with the new method name.
            Buttons are always added to the palette after existing palette buttons. To add a button in any other
            position, just use the Fnd_Nav_Delete to delete all of the existing palette buttons, then recreate the
            palette using Fnd_Nav_AddButtonMethod and Fnd_Nav_AddButtonTable.
              Fnd_Nav_Delete 	  ` Remove all of the buttons.
              Fnd_Nav_AddButtonMethod ("MyCoolMethod";"Run Cool Method")
              Fnd_Nav_AddButtonTable (->[Invoices])
              Fnd_Nav_AddButtonTable (->[People];"Customers")

            You can optionally specify the text color and background color to use for the new button. See 4D’s
            SET RGB COLORS command documentation for more information about specifying colors. Pass the
            4D constant Default foreground color and Default background color to restore the palette’s default
            colors.
                ` Add a button with a light green background color.
              Fnd_Nav_AddButtonMethod ("MyMethod";"Run My Method";Default foreground
