Ctrl + Z: Undo your last action, whether it’s editing text, renaming a file, or deleting a folder. Ctrl + Y: Redo the last undone action, restoring changes without hassle.

Like undo, you can redo the design many times to get the changes back. Alternatively, you can also use Shift+Ctrl+Z as a keyboard shortcut to redo.

Then, if you determined you actually did want to remove it, press "Ctrl-Y" to re-delete it. You might want to redo a previous action that you chose to undo in the event your change was ineffective.

Some apps offer a “redo” option: Tap Ctrl-Y to un-reverse whatever action you just reversed. Or, if you’re more of a menu person, look for Redo in the Edit menu. It won’t be far from Undo.

In the case of PC, 'Ctrl + Z' is used to cancel, and 'Ctrl + Y' is used to redo. The illustration drawn in the ' PARTICLE' part is an illustration that jumps around the character. Click OK when done.
