What function does the Shift-Delete command serve in video editing software?

The Shift-Delete command in video editing software is primarily used to remove a selected clip without leaving a gap in the timeline. This function is particularly useful when you need to delete a clip and want the remaining footage to automatically close the space left behind. By using this command, editors can maintain the continuity of their timeline, ensuring that all subsequent clips are pushed forward to fill any void created by the removal of the selected item. This helps streamline the editing process, allowing for a cleaner and more efficient workflow, especially during tasks such as trimming scenes or removing unwanted footage while preserving the overall sequence integrity.

In contrast, simply deleting a clip without the Shift key typically leaves a gap, and any option that suggests extracting clips or moving them to a separate timeline would not accurately reflect the function of Shift-Delete. Thus, the correct answer accurately describes the intended use of this command in video editing software.
