Navigating a large file system can be cumbersome and often you go to the same directories, so you need z
Install z
After a short learning phase, z will take you to the most 'frecent' directory that matches ALL of the regexes given on the command line, in order.
Now you can jump around - if I want to go to my TIL repository, which I do quite often, I can just do:
z til
You can list your jumping points:
-l list only
And you can remove a directory:
-x remove the current directory from the datafile
