https://macmost.com/e-1438 Users who are new to Mac often don’t know about Spotlight, or think it is just a way to search for files by name. You can use spotlight to search for files by name and content and preview the contents before you open the file. You can also go to the file instead of opening it. Spotlight will also find other items like dictionary definitions, email messages, images and more. You can use Spotlight to do mathematical calculations, unit and currency conversions. One thing that many people use Spotlight for is a quick and easy app launcher.
