Undo
Most changes show Undo for a few seconds. On the computer, ⌘Z (Ctrl Z) does the same, outside text fields.

What you delete goes to the Trash for 30 days. Open it from the bottom of the sidebar (on the phone, in Menu), filter by type and click Restore. Delete forever removes something for good.
