The keyboard shortcut Control + Y is commonly used in various software applications to perform the Redo action. This function allows users to reverse the last action that was undone, effectively restoring it to the document or workspace. It is particularly useful in text editing and graphic design programs, where users may frequently make changes and adjustments. When using Control + Y, it is important to note that it typically works in conjunction with the Undo command, which is often executed using Control + Z. Together, these shortcuts provide a streamlined way to manage changes, enhancing productivity and efficiency in digital tasks.
