On average, I'd say I spend 65% of the workday in a terminal session. About 95% of that time is within the same same 4 directories. cd foo & cd bar can get old. AutoJump is a "cd command that learns". It tracks shell history to detect which directories you spend the most time in, and allows you to jump to them without any directory context. It even supports Zsh tab completion. :)

From this:

cd /Users/kreitz/repos/public/gistapi\

To this:

j gistapi

Life is good.
