Sublime Text 3 is a powerful and easy to use text editor. An ultra simple user interface beautifully hides all the complexity behind. You can start using the editor without knowing any details, which is great for beginners. When I started using Sublime Text, I was a migrant from the world of TextMate and Vim. While a lot of keyboard shortcuts and features were similar to TextMate, some looked alien as well. Earlier, when I was learning Vim, I had found vimtutor to be of great help. In my early days with Sublime, I was looking for a similar solution which could interactively teach new shortcuts inside the editor itself.
