In this chapter, we are taking a step forward from basic zsh usage and diving into the more advanced features of the command line. We will be getting close and personal with the zsh line editor, understanding how it works and why zsh needs it's very own input editor. We will discover new ways of accessing and tapping into the shell's history and learn some new command line editing tricks in order to speed up most of our regular tasks and avoid repeating ourselves to boredom. Finally, we will discover that there's really no need to be limited to a single line of text while using zsh.
