Most of them I already knew, but z seems like an interesting tool. The docs are here <https://github.com/rupa/z>:
z foo cd to most frecent dir matching foo
z foo bar cd to most frecent dir matching foo, then bar
z -r foo cd to highest ranked dir matching foo
z -t foo cd to most recently accessed dir matching foo
z -l foo list all dirs matching foo (by frecency)
