How do I swap two adjacent lines?

Explanation

The ddp sequence swaps the current line with the line below it. It is the line-level equivalent of the xp character swap.

How it works

• dd deletes the current line (saved to register)
• p pastes the line below the new current line
• The result is the two lines have swapped positions

Example

line B
line A

With the cursor on line B, pressing ddp gives:

line A
line B

Tips

• ddkP swaps the current line with the line above
• :m+1 moves the current line down one position (same effect)
• :m-2 moves the current line up one position
• In visual mode, you can use :m'>+1 to move selected lines down
