How to restore a deleted script, sprite, costume/backdrop, or sound

To restore a deleted script, sprite, costume/backdrop, or sound, click on the Edit menu and then click on Undelete (if you're running a previous version of Luckode, it could also be called Restore Previously Deleted Sprite).

Depending on the thing you last deleted, the following will happen:
Script - The script will be attached to the mouse until you click on the code area.
Sprite - The sprite will reappear in the sprite pane.
Costume/Backdrop/Sound - The costume/backdrop or sound will be restored as the last item in its respective tab.

NOTICE: The Undelete option only holds up to one item.
