Marks are Bookmarks

Set Marks to be added automatically during the recording phase. You can also add Marks manually in the editing phase; in the timeline navigate the playhead to where you would like the Mark to appear, then click the + icon above the timeline, a menu will drop down where you can select what happens when the movie reaches the mark. When you have selected an action for your mark a dotted red line with a number at the bottom will appear in your timeline to represent the Mark. To remove a Mark, click on its number and click the - icon above the timeline.

Interactive objects, like click zones and buttons, will automatically add a mark to the timeline that stops the movie to wait for user interaction. Use Marks to automatically navigate to another Mark in the movie or send your viewer to a website.
