When
            you drag a source clip over a target clip, the cursor changes as
            the source clip moves over different areas of the target clip. The type
            of cursor indicates the type of edit that occurs when you drop the
            source clip on that spot.
         
         All gestural splices,
            insert edits, and replace edits ripple the edit sequence; that is,
            they change the duration of the target clip unless you replace a
            clip with another clip of the same duration.

                     |    Insert | The source clip is positioned between frames on the target clip. | Perform an insert edit. | 
                  
                     |    Replace | The source clip is grabbed at any frame other than its
                        first or last frame, and is positioned over a frame on the target clip. | Perform a replace edit. You cannot gesturally replace
                        frames with a two-frame clip. However, you can perform this type
                        of edit with a one-frame clip. | 
                  
                     |   Replace ahead | The source clip is grabbed at its first frame and is
                        positioned directly over a frame on the target clip. | Perform a replace edit starting at the frame under the
                        cursor and moving in the direction of the arrow. | 
                  
                     |   Replace back  | The source clip is grabbed at its last frame and is positioned directly
                        over a frame on the target clip. | Perform a replace edit starting at the frame under the
                        cursor and moving in the direction of the arrow. | 
               
            
          
         To perform a gestural insert or replace edit:
         
         
            - Drag the source clip over the frame in
               the target clip where you want to make the edit until you see the
               appropriate edit cursor.
            
- Drop the source clip.
               The clip is updated with
                  the edit. The source clip replaces the frames of the target clip
