do means you do it and undo means to undo or get ride of it
redo means do something over again and undo means to do it back
You use redo to undo an undo, but you use repeat to initiate the same keystrokes just completed in your typing.
the difference is that inrepeat if you have undo anything and you want it back so repeat brings it back. In duplicate you can get another copy of the thing you have made.
When you undo something you go back to before you made the change. When you redo something you repeat what you have already undone. You have to first do and undo before you can do a redo. So if you undo something and realise that you should not have undone it, you can you use redo to effectively undo the undo.
