Shortcut keys are special combinations of keyboard keys that allow users to perform tasks more quickly than using a mouse. For example, pressing Ctrl + C copies selected text, while Ctrl + V pastes it. These shortcuts can save time and improve efficiency when working on computers or other devices. Many software applications, like Microsoft Word or Adobe Photoshop, have their own set of shortcut keys tailored to their functions. Learning these shortcuts can enhance productivity, making it easier to navigate menus and execute commands without interrupting your workflow.
