If you are using cd to change directory then you are doing it wrong. fasd is an alternative tool which will make you 10x faster. fasd maintains a list of frequently accessed directories and does a fuzzy jump and jumps to that directory.

# Faster Jump

I have added alias "j" to fasd_cd -d fast jump to directories

# Faster open file

I have added alias "vi" to fasd -f -e 'emacsclient -t' fast find my recently accessed file and open it.
