Use vim to open a file full of code (or text) that has some blank lines. Move the cursor to the middle of the file. Then start hitting { or }. You’ll see that the cursor jumps from blank line to blank line.

Use { to jump to the closest blank line behind the cursor. Use } to jump to the closest blank line ahead of the cursor.

This may not seem like the most practical or obvious way to navigate, but it can help move you around a bit quicker than just tapping k and j.
