problem with hash

I'm opening a view and passing multiple key/value pairs within one symbol like so:

<%= link_to 'view', {:controller => 'screens',                      :action => "content",                      :data => {"title" => "Body", "content" => screen.body}} %>

What's the proper way to access these from the view I'm rendering? I can access the params object to get at the info if I'm only passing one value, but I'm having problems getting at both key/value pairs.

I've tried multiple variations of the following with no success:

<%= params[:data["title"]] %>

Thanks,

params[:data][:title] (the params hash is magic so it doesn't matter if you use strings or
keys)
