Under the Bourne shell here's a little example .....

$ CDPATH=:/:/usr	# <-Just like PATH, look in . first, then / then /usr
$ export CDPATH
$ cd /usr		
$ cd bin		# <- finds bin under . so go there.
$ pwd
/usr/bin
$ cd bin		# <- does not find bin under . so now search for first
			#    bin directory un the $CDPATH variable.
/bin			# <- automatically prints out where it found it.
$ pwd
/bin
