Which shortcut is typically used for undoing an action in document editing?

The shortcut commonly used for undoing an action in document editing is Ctrl + Z. This command reverses the most recent changes made to a document, allowing users to quickly correct mistakes or revert back to a previous state without having to manually delete or change the content. It enhances productivity by providing a simple way to backtrack, which is especially useful when errors occur or decisions need to be reconsidered.

In many software applications, including word processors and design software, the use of Ctrl + Z has become a standard convention, making it easily recognizable and accessible for users of all skill levels. This consistency across programs reinforces its importance as a foundational tool in digital document management.
