I've used fzf for finding files at the cli for ages but never realized there was shell integrations.

Adding the zsh shell integrations adds the following which make moving around the filesystem in shell very fast:

Ctrl-R     # search history
Ctrl-T     # search files, insert at cursor
Alt-C      # cd to directory
**<Tab>    # fuzzy completion when you explicitly want it, for command args or whatever, e.g. `ssh **<TAB>` to fzf search hostnames
