Vim edits text with the keyboard alone. Instead of clicking or holding an arrow key, you press single keys that move the cursor precisely, such as one word forward or to the end of a line. Those keys are called motions, and they are what make experienced vim users fast. This game teaches them one at a time.

You're always in Normal mode here, so every key is a command. Put a number in front to repeat (3j moves down three), and if a key seems to do nothing it's usually waiting for a second key, like f then the letter to jump to. The panel tells you when it's waiting.
