What keyboard command can you use to open Spotlight?

The command to open Spotlight on a Mac is Command-Space. This keyboard shortcut is designed for quick access, allowing users to instantly launch the Spotlight search feature, which serves as a powerful tool for finding files, applications, and information on the Mac. The Command key is a central modifier in macOS, and combining it with the Space bar specifically invokes the Spotlight interface.

Using this shortcut saves time and enhances productivity by enabling users to search their systems without needing to navigate through menus or windows manually. Spotlight not only helps in locating files but also provides web search capabilities, information on contacts, definitions, and more.

The other options, while they might be functional combinations, do not serve the purpose of launching the Spotlight search. Each modifier key (Control, Option, Tab) combined with others like Shift or Space performs different functions that are not related to Spotlight. Therefore, Command-Space is the specific and correct choice for activating the Spotlight feature.
