title: Column/Vertical selection with Keyboard in SublimeText 3
body: <p>I'm on a Mac. I have 7 columns in Sublime Text 3, each 300 lines each. If possible, I would like to select only the 4th column using a single keyboard shortcut. </p>
  
  <p><em>Unsuitable options</em></p>
  
  <ul>
  <li><code>ctrl</code> + <code>shift</code> + <code>up/down</code></li>
  <li><code>alt</code> + <code>mouse</code> + <code>drag</code></li>
  <li><code>ctrl</code> + <code>alt</code> + <code>up/down</code>. (This actually doesn't do anything, nor does it appear in my console session and nor is it a single keyboard shortcut).</li>
  <li>I'd also prefer not to use VI/VIM mode just for this as it's not regular part of my workflow</li>
  </ul>
  
  <p><em>What I've tried:</em></p>
  
  <ul>
  <li>A macro: but it isn't specific enough. </li>
  <li>using <code>command</code> and 'page down' with <code>ctrl</code> and 'shift`: no luck</li>
  <li>SublimeText 3 Column-Select plugin: did not seem to work for me</li>
  </ul>
  
  <p>My ideal solution would be that my cursor could be placed anywhere in a column and I would hit a shortcut (e.g. ctrl-alt-shift-a) and it would select the whole column. </p>
  
  <p>Here is an example:</p>
  
  <p>John         Sally      Benson       Mariah      Patrick    Samantha    Martin</p>
  
  <p>Simon        Kate       Carey        Delores     Joshua     Samuel      Eliza</p>
  
  <p>I want to select the column with Maria and Delores with one keystroke. I perform this action often so for various reasons (cut/paste, change case, append, add quotes, run macro etc) and thus would want something quick and repeatable.</p>
  
  <p>How would I do this?</p>
