title: How to hunt down a rogue keybind in Vim
body: <p>Any time I launch vim, there is a mysterious keybind on the key <code>Y</code> that breaks the regular yank functionality. In the output of <code>:map</code> it looks like this:</p>
  <pre>
  n  Y           * y$
  </pre>
  <p>I should be able to see where it comes from by typing <code>:verbose :map</code>, but to my intense frustration, this is the <em>only</em> key mapping in the entire output with <em>no origin</em>:</p>
  <pre>

  <p>So, short of disabling my plugins one by one until I find the culprit, is there any way to further troubleshoot the origin of this keybind?</p>
