During work on a document, the translation of a segment undergoes multiple changes. The system keeps track of all of them. All revisions of the current segment are displayed on the Revisions tab at the bottom of the page.
You can restore any of the revisions by selecting the revision and clicking Restore. The revision you selected will be displayed in the Target field.
The Revisions tab can also help if you need to evaluate the quality of a translator’s work. You can see all changes made by the editor or proofreader, and compare the initial and final translations. In turn, the translator can also view the changes made by the editor, and in so doing learn from any mistakes and avoid them in future.
