sublime text ruby .erb block comment keyboard shortcut?
===

I'm looking for a shortcut in sublime text 2 that will make a block comment in a .erb file.

For instance say I have this block of code in my .erb

    <% @posts.each do |post| %>
      <p>my code</p>
    <% end %>

And I want to quickly comment out the whole thing like:

    <% 
    =begin %> 
    <% @posts.each do |post| %>
      <p>my code</p>
    <% end %>
    <% 
    =end %>

Is there a way to highlight that chunk and hit a keyboard shortcut to add those comment blocks? I've tried highlighting the block then choosing Edit > Comment > Toggle Comment and Edit > Comment > Toggle Block Comment but nothing happens.

I have the ERB Insert and Toggle Commands package installed but maybe I need something else?
