Hello! Click this region to activate me and start learning about Vim! Let's jump right to it! Vim is a "modal editor", meaning it has different modes. When you open vim, it opens in COMMAND mode. If you ever find Vim in a different mode (or if your controls are acting wonky), simply press ESC to re-activate COMMAND mode. Great! We'll start with basic navigation. To move around in Vim, press: ^ k < h l > j v l - move right h - move left j - move down k - move up Time to practice! Try going right (l) and left (h). Now try moving down (j)! Let's move back up (k). Stray away from the [[arrow keys]]! It may seem easier to use the arrow keys, but those two seconds you take to move over to use them can actually add up to a lot on the course of your programming career! Let's try navigating through this haiku: Yay, we are learning how to navigate with Vim This is so much fun! We can make moving around more efficient using a numerical modifier. Simply precede the command with an value [0-9]. For example, pressing '4h' moves 4 characters to the left. Review Questions: 1) Why are we learning Vim?
