I've found which, I think maybe someone else pointed out, a bug. Take any book, use the BookPort's "find" feature with chord f, braille in "book," and press the lower key on the far end of the second row, right hand most which is enter. By the way, there should be a reference to which row is which when describing the braille layout, I.E. With the unit in the proper position, keys facing up with the lip of the removable memory card facing your body, first row: 3, 2, 1, 4, 5, 6. second row: Escape, Left, Up, Down, Right, Enter. third row: 7, BackSpace, Space, Space, Delete, 8. One of the "space" keys, the fourth from the left on the third row does not work for chording commands. In a forward search, with "book" as an operative word, if the word is contained inside another word like notebook, the forward search will not continue from that point, I have to go past the occurrence of that word in order to find other "books" as it were. In a reverse search, it works fine. I sent a "*.kes" book from Kurzweil 1000 to Bookport which had regional settings in it I.E. chapters book marked, however, somehow either K1000 did not send the marks or BookPort did not translate them, I don't know which yet.
