If you wish, you can add undo and redo icons to the Quick Access Toolbar at the top of the Explorer window by clicking on the icon of a downward pointing arrowhead with a horizontal line above it (the red arrow on the image below points to it) that appears at the top of the Explorer window.
You can then select "Undo" and "Redo" from the menu that appears.
Select both, so that you see checkmarks next to each of those options.
You should then see curved Undo and Redo arrows next to the button you clicked on for the Customize Quick Access Toolbar.
You can now use those arrows, in addition to the shortcut keys, if you prefer to undo and redo actions in the File Explorer.
