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.
