I am new to computer applications, and interested to know what the function of UNDO command is and how to use it. Can anyone give a brief description of this command?
Undo command is nothing but revert or roll back to the most recent change you made.
It is the feature of the computer program where one can go back to the last command executed.
The shortcut for Undo command is:
• In Windows: Ctrl+ Z or Alt+ Backspace
• In Apple: Command +Z
Some examples where you find the Undo command are
1. In Microsoft tools like Microsoft word, excel, etc.
2. In Email system when you delete an email.
3. In database when a transaction is performed.
4. There are many other applications which provide this undo option.
Caution: Once you have closed the application, you cannot UNDO any changes.
