I've just received my Bookport. I previously had a Bookcourier. With the Bookcourier I was able to move through the Audible title by seconds, 5 minutes, ten minutes and by section. This doesn't seem to be possible with the Bookport. Is this the case? I also can't seem to get the bookport to report the battery status by pressing d+f on the braille keyboard. I stop listening to a file with the 2 key then try to type d then f on the Braille keyboard. Thanks Paul
