Computer shortcuts are key combinations or commands that allow users to perform tasks quickly without 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 a computer. Many software applications, including Microsoft Word and Adobe Photoshop, have their own specific shortcuts. Learning these can help users navigate programs more effectively and streamline their workflow. Overall, computer shortcuts are valuable tools for enhancing productivity in various digital environments.
