When we watch Youtube videos we always have new videos in mind which we want to see and need to search for them . But leaving your current video or opening a new tab is always difficult . So YT Background Search adds a BG Search button with the original search button as shown below.
You just have to type the search query and click on BG Search button . You will see a drop down menu with the search results within the same page and above your current running video . So you don’t have to leave your current video to perform a new search , that’s how easy it is.
