The Undo button often appears as a curved arrow pointing to the left, while the Redo button usually shows a curved arrow pointing to the right. In addition to the toolbar, these functions can often be accessed through keyboard shortcuts, such as Ctrl+Z for Undo and Ctrl+Y for Redo on Windows, or Command+Z and Command+Shift+Z on macOS.
