What executes commands with other keys?

Commands are executed with other keys through the use of keyboard shortcuts or key combinations, which involve pressing two or more keys simultaneously. For example, in many software applications, pressing "Ctrl" + "C" copies selected text, while "Ctrl" + "V" pastes it. These shortcuts enhance efficiency by allowing users to perform actions quickly without navigating through menus. Additionally, function keys (like F1-F12) often have specific commands assigned to them, depending on the application.
