What does the REDO function shortcut, Ctrl + Y, allow you to do?

The REDO function, activated by the shortcut Ctrl + Y, allows users to reverse the most recent undo action. When a user mistakenly removes or alters something in a document and then decides they want to reinstate that change, using the REDO function is essential. This function effectively restores the previously undid action, making it highly useful for editing tasks where multiple changes are made, and the user wants to revisit previous states of the document. Thus, this shortcut serves to streamline workflow, enabling users to correct mistakes efficiently without manually redoing their work.
