During multiple-row editing, you can restore field edits on any item up until saving changes to the server. When an item with field edits is active, selecting > or clicking the corresponding toolbar button

restores the original values for all edited fields. The
Restore Field Edits action is available only when a single item with field edits is selected. This action restores all field edits on the item to the values originally on the server.
You can also restore all field edits to a single item after a resynchronization. For more information, see
Restoring Field Edits on an Item After Resynchronizing.
