What does the keyboard shortcut Ctrl + Y specifically do?

The keyboard shortcut Ctrl + Y is commonly used in various software applications to redo the last action that was undone. This means that if you made a mistake and used the Undo function (typically Ctrl + Z), pressing Ctrl + Y will reverse that undo action, restoring the previous state that was just undone. This functionality is particularly useful in situations where you inadvertently remove or alter content and wish to reinstate it without manually redoing the steps taken.

In text editing or graphic design applications, for instance, this shortcut allows for efficient workflow management by enabling users to quickly correct errors without extensive navigation through menus. This function is part of the standard keyboard shortcuts found in many applications, enhancing user experience by facilitating quick command executions.
