Questions tagged [undo-redo]

For issues relating to undo and/or redo operations.

In graphical use interfaces, Undo is a command used to erase the last (text or command) change done to the document reverting it to an older state. Redo is a command that reverses the undo or advances the buffer to a more current state.

Common key bindings for undo include Ctrl+Z or Command-Z, and common key bindings for redo include Ctrl+Y or Command-Shift-Z.
