Undo
Undo is a command in most word processors and text editors. It erases the last change done to the text buffer reverting it back to an older state. In some more advanced programs such as graphic processing , undo will negate the last command done to the file being edited.
On most Windows machines, the Undo command is activated by pressing CTRL-Z.
