I have discovered that when I press the central key of the joystick one option is Dictionary. Then it appears at the botton of the page with three icons for options. You can move accross there with the keys and, if you press the left key up to the name of the dictionary and press is you will see the dictionaries that you have installed into your device (on the dictionary folder, no cd3/dict, but system/dict).
I don't know if you have undestanded my "indian" explanation (or I din't understanded your question
)
