It has happened to me more than once that, for example, when keying the Shelf Mark I accidentally hit the "enter" key instead of the "period" or "full stop" key on my keypad. This saves the record with an incomplete or incorrect Shelf Mark and prompts me to match the next record. Is there a way to get the previous record back? I've tried tinkering with the URL which seems to end in a record number, but this doesn't seem to do what I want it to. Is there a solution? Thanks!
