Which keyboard shortcut initiates a Rolling Edit?

The keyboard shortcut that initiates a Rolling Edit is the letter R. A Rolling Edit allows you to adjust the in and out points of two adjacent clips simultaneously without affecting the overall duration of the sequence. This is particularly useful in video editing because it enables you to fine-tune your timeline efficiently, ensuring that cuts are made smoothly and in sync with the pacing of your project.

Using the Rolling Edit tool ensures that as you shorten one clip, the adjacent clip extends to fill the gap, keeping the flow and rhythm of the edit intact. Additionally, this tool is essential for precise adjustments in narrative films, music videos, and any project where timing and transitions are critical.

The other options do not correspond to the Rolling Edit function; they may be related to different editing tools or shortcuts that perform other tasks in your editing workflow, but they do not initiate a Rolling Edit. Understanding these shortcuts and functions is key for effective video editing.
