Shortcut to comment in html.erb

Hi,

I am testing out rubymine and one of the things I like is in the integrated functionality as opposed to ST2. I don't have to spend time configuring ST2 since the rubymine IDE is very featured out-of-the-box. With that said, the comment shorcut cmd+/ does not seem to work for embedded ruby (<%= =>) in html.erb files. In other words, if i have something like:

<%= render 'layouts/header' %>

in application.html.erb and I want to comment that code out, the shorcut does not work.

How do I get it to work?

Thanks

Yko
