title: Autocomplete not working well in visual studio code
body: <p>I'm getting started with Visual Studio Code and have been a user of Atom. One thing I've noticed, particularly with autocomplete for PHP, I have to scroll through a list of options in order to find the option to automatically fill in code. I want to get the autocomplete just by hitting tab.</p>
  
  <p>Say, for example, I want to make an <code>if</code> statement. In Atom, I just type "if" then hit tab and it will fill in the code with everything I need. In VS Code, if I type "if" followed by tab, nothing will happen. I would have to first scroll to the specific option. Is there a way to just get autocomplete by typing in the keyword then pressing tab?</p>
  
  <p>This issue also applies to <code>elseif</code>, <code>else</code>, <code>while</code>.</p>
