Moving lines also requires two commands: dd (“delete”) and either p or P.
To move one line, position the cursor anywhere on the line and type dd. For example, to delete 5 lines, type 5dd.
Next, move the cursor to the line above where you want the deleted line reinserted and type p. This inserts the text on a new line below the cursor.
Alternatively, you can put the deleted line above the cursor by typing P.
