I use the search feature to quickly navigate through directories. I have 'CD on exit' configured as well so I can quit 'fff' and I'm in the new directory ready to type commands.

I also like that I can hit 'l' (or enter) to open files and I don't have to think about what program I need to use to open them. Text files are handled by '$EDITOR' and everything else is opened through mime-type using 'xdg-open' (which is configurable to your opener of choice).
