If you press CTRL + F (or F3) it opens up the "CTRL + F" search bar at the bottom of the browser. But in my experience, if I want to close that search bar, I have to manually do it by moving my mouse to the bottom right corner of the browser and clicking the search bar close button. In most applications that I ever used, I could press "CTRL + F" a second time to toggle the search off. Is there a shortcut key that I can use to toggle the search bar off so I don't have to keep manually closing it?
