You press the "Select" button to look up the highlighted word. MobiPocket sell a very wide range of dictionaries which will work on the Gen3, both general-purpose and specialist (such as the various Oxford dictionaries of art, architecture, classical literature, religion, etc etc).
I just placed the Oxford Advanced Learner's Dictionary on the SD card, but when I try the lookup mode from within a mobipocket book, it tells me no dictionary is available for this language (which is English).
Do you know where I have to place the dictionary to make it available?
