What modifier key is used to perform an insert edit when dragging clips to the Program Monitor?

The correct modifier key used to perform an insert edit when dragging clips to the Program Monitor in video editing software is the Ctrl key. When you hold down the Ctrl key while dragging a clip, the software essentially adjusts the timing of the edit to insert the new clip into the timeline at the selected position, pushing any existing clips forward to make room for the new one. This allows for an efficient way to integrate new footage without overwriting existing elements, preserving the overall structure of the sequence.

The other keys mentioned do not serve the same function in this context. For instance, while the Shift key is commonly used for constraining movement or aligning elements, it does not facilitate an insert edit. The Alt key typically serves different functions, like creating duplicate clips or performing specific commands unique to the editing software. The Esc key is primarily used to cancel operations or exit modes, rather than facilitating editing actions such as insert edits. Understanding these key functions is crucial for efficient editing workflows in video production.
