The thumbnail toolbar gives you a quick overview of the paper you are currently grading

1. The thumbnail toolbar can be accessed by clicking on the "black tab" in the left-hand corner of the Turnitin Feedback Studio.
   
   
2. Click on one of the thumbnails to jump to the relevant page within the paper.
   
   
   
3. You can "lock or unlock" the thumbnail toolbar using the padlock icon in the top left-hand corner of the thumbnail toolbar; this will resize the paper to fit your current view. Note: Locking the thumbnail toolbar will prevent you from being able to close it.
   
   
4. To close the thumbnail toolbar, "unlock" it by clicking on the locked padlock icon, then click the "black tab" that was originally used to open it.
