Yep "Up" and "Down" on the "joystick" switch you through the various info screens during review. You can turn on/off which info screens are available in the camera menus.
This was definitely odd for me coming from the Canon side. There is that nice big juicy "Info" button right next to the screen that looks as if it would flip you through the different info screens during review... but alas... it is mostly useless (giving you the same info that is on the LCD for the most part). ;-)
