A small but extremely useful shell script which can be run with the 'f' command. It fuzzy finds over a subset of directories and pulls the path I want. I can then pick from a series of small workflows with a single keystroke such as jumping to the directory and running a 'ls', opening the file, opening the file in a text editor, opening the file in Mac finder, searching for text within the file or directory, etc. It has mostly replaced most terminal navigation and has been extremely useful.
