This is blatantly taken from HI as this I think is useful enough to repost nearly verbatim.

If you’ve ever needed to know exactly which Client Scripts, UI Policies, and UI Actions are loading onto the page when you view a form or Service Catalog item in Service Portal, the information is readily available if your know where to look.

If you are using the out-of-box “SC Catalog Item” and “Form” widgets, you can find this information in the widget’s scope.

To view the widget’s scope, hold down the CTRL key and right-click anywhere in the widget. Choose “Log to console: \$scope”. Open your browser developer tools to the JavaScript console. Expand the “Object” that has been dumped to the console.
