What is the Redo Shortcut Key in Computer?

Consider the situation of writing a report in Microsoft Word and deleting a paragraph by mistake, you undo the deletion by using Ctrl Z to reapply the deleted paragraph. Then later you find that it is correct to delete the paragraph, but instead of deleting the text again you can just redo the command with Ctrl Y.
This simple process saves time and reduces repetitive work.

| Undo | Reverse the previous action |
| Redo | Restore the undone action |
| Repeat | Repeat the last completed command |
