So on the right most side of your LibX add on tool bar there's a diploma with the word Scholar next to it. If you click it, a pop up will tell you to select search terms and drag them to the button.
So if you see a term and you think to yourself "I wonder if there are any scholarly articles on that", select the term with your mouse. Then click and drag the selection and drop it on top of the word scholar.
And there you have Google Scholar search results.
