Can you also include things like shiftKey, ctrlKey and metaKey?

+    disposition = NEW_BACKGROUND_TAB;
+  } else {
+    CHECK(button_string == "0");
+    disposition = CURRENT_TAB;
+  }
+
+  dom_ui_->tab_contents()->OpenURL(
+      GURL(url_string), GURL(), disposition, PageTransition::LINK);
+
+  // This may delete us!
