What key combination do you use to show the location of a file using Spotlight search?

The key combination to show the location of a file using Spotlight search is Command and Option. When you have performed a search in Spotlight and found the item you are looking for, pressing these keys will highlight the item in Finder, allowing you to see its actual location in the file system. This functionality is very helpful for users who want to quickly navigate to the file without having to manually browse through folders.

The first option involves Command and R, which does not serve the function of revealing a file's location in Finder. It generally relates to different system commands that are not specific to Spotlight. The second option, Command and Shift, does not provide any direct functionality tied to Spotlight searches. Lastly, Control and R is not a recognized key combination for interacting with Spotlight or Finder and does not pertain to showing file locations in a practical context.
