#if the directory is an existing directory, then jpInsert-cd to it. If not, 
#then it might be a deleted entry. Remove this from the hash so we won't 
#go back to it again. This directory might actually exist, though (it's just
#not hashed yet). If so, try going to it with jpInsert-cd. 
#in find, the unhashed path gets priority. First check to see if the key's path exists,
#then, find it from hash as last choice
