title: Vim: How to yank a visual block to a register?
body: <p>I can yank a line to register <code>a</code> by <code>"ayy</code>. </p>
  
  <p>But I am not able to figure out a way to yank some visually selected block to a particular register. If I just press <code>y</code> after selection, it stores it in the default register. But I need to store it in a specific register, how can this be achieved?</p>
