After searching, users may need to mark up the searched text strings in a highlight color. With Foxit PDF Editor’s Search & Highlight feature, users can perform an advanced search and highlight the searched text strings with one click.
- Choose Comment > Search & Highlight. (Or click in the Search box on the title bar and choose Search & Highlight from the drop-down menu.)
- The Search panel opens. Search the text strings or search by patterns as needed.
- After the search completes, you can see a Highlight icon
next to the Save button 
in the Search panel, a check box in front of each searched instance and each file path, and the Check All option above the New Search button. - Select the check box of the instance you want to highlight and click the Highlight icon
. (Tip: Click the check box in front of a file path to select all instances found in the file; select the Check All option to select all instances found in the search.) - (Optional) you can also change the highlight color as needed. Change the color from the appearance properties of the markup and set the properties as default. (For details, please refer to Change the appearance of Text Markups.) Then perform a new search to apply the new color to searched results.
