Larry, I have some teach-yourself foreign language lessons in MP3 format. The user is supposed to listen to the spoken text, and then to repeat it frequently. That means one constantly has to rewind a few seconds worth of material in order to listen to a phrase again. How suitable is the Book Port for this kind of task - listening to spoken text in MP3 format and skipping back and forth within the MP3 file in order to review difficult phrases? I guess what I am asking is whether Book Port has anything anything akin to a fast forward/reverse function with regard to MP3's. Peter
