What does the "Ctrl + Z" command do?

The command "Ctrl + Z" is universally recognized as the shortcut for undoing the most recent action performed in many software applications, including word processors and graphic design programs. When you use this command, it effectively reverses the last change made, allowing users to correct mistakes quickly and efficiently. This function is especially useful in editing environments where mistakes can happen frequently, giving users the flexibility to experiment without the fear of permanently altering their work.

In contrast, other commands serve different purposes: redoing actions typically involves a different shortcut, closing applications is unrelated to the undo function, and copying selected text is accomplished with another command. Understanding the specific functionality of "Ctrl + Z" reinforces the importance of knowing keyboard shortcuts for enhancing productivity and streamlining workflow.
