title: Move cursor x lines from current position in vi/vim
body: <p>Is there a way to move the cursor a relative amount of lines in vi/vim? Say you have the cursor 10 lines under a block of code you want to remove. If you have the line numbers shown in relative order, it would be nice to have a "jump 10 lines up command" that would take you there.</p>
  
  <p>Or perhaps it's better to have the absolute line numbers shown and go xgg where x is the line number?</p>
