Spotlight on your Mac
Spotlight 
is an easy way to find anything on your MacBook Pro, such as images, documents, contacts, calendar events, and email messages. You can also use Spotlight to open apps or perform quick actions, like creating a timer.
Search for anything. Click at the top right of the screen then start typing. You can also press the Spotlight key (F4) on your keyboard. With Live Text, Spotlight can search for text in images. Not all languages are available.
Tip: Press Command–Space bar to show or hide the Spotlight search field.
Open an app. Enter the app name in Spotlight, then press Return.
Perform quick actions. You can quickly do certain tasks with Spotlight, like running a shortcut, starting a Focus, or setting an alarm. Open Spotlight, then search for the action you want to perform.
Convert currencies, temperature, and measurements. Enter a currency—like $, €, or ¥—and an amount, then press Return to get a list of converted values. Or specify a unit of measure for measurement conversions.
Narrow your search. You can include or exclude specific folders, disks, or types of information (such as email or messages) from Spotlight searches. Click Siri & Spotlight in System Settings and go to “Search results” on the right and select or deselect categories you want to include or exclude from your Spotlight results.
Use Siri Suggestions. Siri Suggestions offer info from Wikipedia articles, web search results, news, sports, weather, stocks, movies, and other sources when you search with Spotlight.
If you want Spotlight to search only for items on your MacBook Pro, open System Settings, click Siri & Spotlight, then click to deselect Siri Suggestions in the list of Search Results. You can also make other changes to the list of categories Spotlight searches.
