title: How to see all available variables in handlebars template
body: <p>I'm working on my first Ember.js app and am having some trouble connecting all the dots.  It would be really helpful if I could just see all the variables available within a given handlebars template.</p>
  
  <p>There is a related question, but you have to know the variable that is in scope to use it:

  <p>How can I output <strong><em>all</em></strong> the variables?</p>
