Help with Editor

Where can we find, or can you tell me how to move to the next item in our editor search?
 
We have 5 files opened and are looking for a particular string in each file.  We use the "Find in File" however, we don't know how to go on to the next found item.
 
Any help is appreciated.
 
Thanks,
