You
            can remove elements from the timeline without removing their track.
         
         To delete elements from the timeline:
         
         
            - Do one of the following:
               
                  - Select the elements, drag them to the
                     bottom of the screen and release when the cursor changes to a green
                     recycling icon. You can also select an element and press Alt+D.
                  
- Place the cursor over the element that
                     you want to delete, press the Context key
                     (beside the Ctrl key on
                     the right side of the keyboard), and select the Delete option from
                     the list that appears.
                     NoteIf you place the
                           cursor over an element, make sure there is no explicit selection
                           on another element.
                         
 The selected elements
                  are deleted. Unselected elements remain on the track.
