The undo function is used to reverse a mistake, such as deleting the wrong word in a sentence. The redo function restores any actions that were previously undone using an undo. Some people may refer to this feature as a reverse undo.

For example, if you typed a word, and then deleted it using an undo, the redo function restores the word you deleted ("undid").


On the PC, the keyboard shortcut to redo is usually Ctrl+Y or Command+Y.


If the redo option is available, but nothing was undone, the redo option does nothing.

On Unix-like operating systems, the redo command allows users to restore something undone in the vi or vim text editor. While in vi or vim, pressing Ctrl+R executes the redo command.
