Browsers often use a different shortcut for Redo to match standard "Undo" logic (using the Z key):
To use the redo shortcut effectively, you must first perform an "Undo" action using Ctrl + Z. Once an action has been reversed, pressing the redo keys will "undo the undo," bringing your work back to its previous state.
Web browsers like Google Chrome, Microsoft Edge, and Mozilla Firefox generally prefer Ctrl + Y for redoing text entries or form selections. If you are working in specialized environments like VS Code or other text editors, you may find that Ctrl + Shift + Z is the more reliable option.
