You can set bookmarks on events in a trace file, when you are using the CTF Viewer. Bookmarks enable you to navigate quickly.
               Bookmarks behave as follows: 
               
            
 
            
             
               
               - You can add a bookmark to an event, by right-clicking the event and clicking 
                  Add Bookmark. 
                  
               
- Bookmarked events are shown in the main CTF View by a blue bookmark icon in column one of the event. They are also displayed
                  in the Bookmarks view. 
                  
               
- Double-click a bookmark in the Bookmarks view to jump to the bookmarked event in the Viewer. If the bookmarked event is in
                  a file that isn't open, the file is automatically opened. 
                  
               
- You can select multiple events in the main CTF view and set bookmarks on them all. You can also select multiple bookmarked
                  events and remove their bookmarks. 
                  
               
- Bookmarks persist between IDE sessions.
