What action does the shortcut Command + Z perform on a Mac?

The shortcut Command + Z on a Mac is widely recognized as the universal command for undoing the last action. This is an essential function in many applications, including graphic design and word processing software, allowing users to easily reverse their most recent edits or changes. By utilizing this command, users can quickly correct mistakes or modify their current work without the need for extensive steps or manual adjustments.

This efficient mechanism enhances productivity, enabling a smoother workflow by granting users the ability to revert back to a previous state in their project.
