Hello< When inputting computer braille in the search feature of BP, be careful to use the correct dot configurations. Concerning the finding of the number 1991, you should enter dot 2, dots 3 and 5, dots 3 and 5, and then dot 2. You received the quote symbol by using dot 5 instead of dot 2 for the number one. Incidentally, a friend has fashioned a holder for BP for inputting the computer braille. It's nothing fancy, just a block of wood with a recessed area to accommodate the belt clip. It sure helps inputting the correct symbols by holding the unit steady. Paul Miller
