title: Mapping keys on numerical keypad
body: <p>For years now I've been using laptops - without numerical keypads on their keyboards. Having recently acquired a dekstop keyboard ... just today I found out that Vim's mapping to numbers (1 ... 9, 0) don't work on their numerical keypad equivalents. What I mean? </p>
  
  <pre><code>nmap 1 Dj
  </code></pre>
  
  <p>doesn't work on the numerical keyboard 1?</p>
  
  <p>Is there any solution to this problem <em>(not really a "problem", but annoying)</em>?</p>
