Easy undo
Updated: 12/31/2020 by Computer Hope
Quickly undo mistakes in many Windows programs by pressing the keyboard shortcut Ctrl+Z. For example, if you mistakenly cut or deleted text in Microsoft Word pressing Ctrl and Z at the same time would undo that change.
Multiple undo
Most Windows programs also support the ability to undo multiple changes. Continuing to press Ctrl+Z undoes one change at a time often back up to 12 or more changes.
Redo the undo
If you undo something mistakenly, pressing Ctrl+Y redoes the undo.
