Arduino + Smartie LCD

Hope I'm not in the wrong board.

I've successfully got LCD Smartie working on my Arduino + LCD Keypad Shield.

For the next step, I would like to use "Menu plugin" of LCD smartie and control it by the buttons on LCD keypad shield, but I have complete no clue on how to have it work... could somebody kindly give some tips / suggestions or even examples ? (Google doesn't seems help this time...) Many thanks ~!
