Summary
In this chapter, we have discovered what vi/vim is and the fact that we can use it freely with all the shortcuts we mastered. It is important to know that vi functionality is huge and never-ending; hence, it can't be covered in one chapter and needs a whole book for it. We covered the basics.
I recommend having the vi graphical cheat sheet that can be found at http://www.viemu.com/a_vi_vim_graphical_cheat_sheet_tutorial.html. Keeping a copy under your keyboard can be really helpful.
The next chapter will guide us on how to use Sublime for testing with several languages such as PHP and Ruby.
