In computing, undo (short for undoing) is the ability to reverse the effects of one or more actions. The undo command is usually available in the edit menu of a software application.
Undoing a single action is often quite simple. For example, in a word processor, the user might select the “undo” command from the Edit menu after typing a word by mistake. This would reverse the last typed character.
However, undoing multiple actions can be more complicated, especially if the application stores undo information in a history buffer. In this case, the “undo” command might not only reverse the most recent action, but also all of the actions that were taken after that.
Some software applications also allow the user to redo actions, which will reverse the effects of the “undo” command.
There are many ways to undo in computer. The most common way is the keyboard shortcut. For example, the shortcut for undo in Microsoft Word is Ctrl+Z. Another way to undo is to use the menu. For example, in Microsoft Word, the undo command is under the Edit menu.
