title: Move entire line up and down in Vim
body: <p>In Notepad++, I can use <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Up</kbd> / <kbd>Down</kbd> to move the current line up and down. Is there a similar command to this in Vim?  I have looked through endless guides, but have found nothing.</p>
  
  <p>If there isn't, how could I bind the action to that key combination?</p>
  
  <p>Edit: Mykola's answer works for all lines, apart from those at the beginning and end of the buffer. Moving the first line up or the bottom line down deletes the line, and when moving the bottom line up it jumps two spaces initially, like a pawn! Can anyone offer any refinements?</p>
