No one answer my question. So I guess it must be bug because I can not make GPS moves precious after I made my mistake to command. It is very serious business. For the example, There were 43 list around me. I surfed many places until I read the new name of the business. I press Space+f for full address or information but I was wrong. I can not remember which the correct command but I do not want to start over again. What a waste time? Leslie--
