Extract

Deleting is a you delete but nothing slides over. After doing that you have to ripple delete. Extracting is used so you can cut and delete at the same time. When you have extracted you have the ripple delete option. You have to choose in and out points where you want the extraction in the program panel. You also have to right click on the gap area that you want to ripple delete. By ripple deleting it grabs all the clips together and slides them over.
