Answer 1

Cmd+"Z" undoes the previous action, while Cmd+Shift+"Z" redoes an action that was undone. Option 1 is correct as it corresponds with the standard use of these shortcuts in Mac OS.

Step-by-step explanation:

The result of Command (Cmd)+"Z" on a Mac is to undo the previous action, while the result of Command (Cmd)+Shift+"Z" is to redo the action that was just undone. Therefore, the correct answer to your question is option 1) Cmd+"Z" is used to undo the previous action, and Cmd+Shift+"Z" is used to redo the previous action. This common keyboard shortcut pattern is used in many applications for Mac OS, such as word processors, graphic design programs, and others.
