Which shortcut is used to “Undo” the last action?

Keyboard shortcuts are essential for efficient computer usage. The universal shortcut used to "Undo" the last action in most applications, including MS Word, is Ctrl + Z. This command reverses the most recent change, allowing users to correct mistakes or revert to a previous state of their work.

• Ctrl + Y is commonly used for "Redo," which reverses an "Undo" action, reapplying a change that was previously undone.
• Ctrl + A is used to "Select All" content within the active document or window, highlighting everything for further action.
• Ctrl + X is the shortcut for "Cut," which removes the selected content from its current location and places it onto the clipboard, ready to be pasted elsewhere.
