The highlight button near the top of the document viewer will highlight entities found in the documents. Click the highlight setting button (
) on the left to toggle between highlighting and no highlighting. Use the button just on its right to switch between All and Current Search. When All is selected, all entities found in the document will be highlighted. When Current search is used, the system will only highlight based on the search criteria used.
The arrows allow navigation to the previous or next annotation. The marker icon furthest to the right allows you to engage in user annotation by highlighting.
