What is the shortcut key to "undo" last action on a Microsoft word page?

The shortcut key to "undo" the last action on a Microsoft Word page is "Ctrl + Z". When you perform an action on a Word page, such as typing, deleting, formatting or copying text, you can undo that action by using the "Ctrl + Z" keyboard shortcut. This will revert the page to the state it was in before the action was performed. For example, if you accidentally delete a sentence, you can press "Ctrl + Z" to undo the deletion and restore the sentence. The "Ctrl + Z" shortcut is a very useful and commonly used feature in Microsoft Word as it allows you to quickly correct mistakes without having to manually undo each action. It can be used multiple times to undo several actions in a row. If you want to redo an action that was previously undone, you can use the "Ctrl + Y" keyboard shortcut. In summary, the "Ctrl + Z" keyboard shortcut is used to undo the last action performed on a Microsoft Word page, allowing you to easily correct mistakes and restore the previous state of the page.
