- I did something similar a while back using Norton's Disk Editor and modifying
- CD (in command.com) to ZZ and then used a program called Led's Change Directory
- (LCD) (renamed to CD on my system). This way whne I typed CD I had the
- 'smart' change directory program try to match the closest directory to what
- I typed. It was quite useful.
