undo function
Cancel last action
An undo function reverses a previous action, restoring something to its earlier state.
In software, it cancels the last edit or command: I accidentally deleted the paragraph, but the undo function brought it back.
Most applications use Ctrl+Z or Command+Z to trigger it.
The feature has become so expected that its absence feels like a design flaw.
