If you are looking for a specific type of result, like a bookmark or open tab, you can speed up the process of finding it by typing in special characters in the address bar separated by spaces:

• Add ^ to show only matches in your browsing history.
• Add * to show only matches in your bookmarks.
• Add + to show only matches in bookmarks you've tagged.
• Add % to show only matches in your currently open tabs.
• Add # to show only matches where every search term is part of the title or part of a tag.
• Add $ to show only matches where every search term is part of the web address (URL). The text “https://” or “http://” in the URL is ignored, but not “file:///”.
• Add ? to show only search suggestions.
