To jump to a topic using bookmarks, click the 
icon on the left Navigation pane to open the Bookmarks panel. And then click the bookmark or right-click the bookmark and choose Go to Bookmark.
If you want to hide the Bookmarks panel after you click a bookmark, click the Options menu at the top of the Bookmarks panel and select Hide After Use, which makes the document area wider and improves the reading experience. To keep showing the Bookmarks panel after you click a bookmark, deselect Hide After Use.
To quickly search and find the specific bookmarks, input the keywords in the Search box in the Bookmarks panel. Foxit PDF Editor will list all the bookmarks matching your search with the keywords highlighted in yellow.
Tips:
- If a bookmark is too long to be displayed in the Bookmarks panel, you can right click the bookmark (or click the Options menu
at the top of the Bookmarks panel) and select Wrap Long Bookmarks to wrap it to multiple lines for a better view. To unwrap, deselect Wrap Long Bookmarks. - Clicking the Find Current Bookmark
icon at the top of the Bookmarks panel highlights the bookmark corresponding to the content in the current document view, which can be helpful to find a bookmark as well as show you where you are.
