Think of this as an auto-CDPATH. With CDPATH you have to explicitly add the directories. And even with CDPATH, it won't work if you need to go deep down. As an example, say I have ~/Programs/Firefox/Profiles/kdskdj/Cache. Most people would put just ~/Programs or ~/Programs/Firefox into CDPATH. If you want to get to the Cache directory, you still need to know "Profiles/kdskdj/Cache". With z, if you're lucky, you'll just do "z Cache". Worst case, "z Fire Cache"
