What is the result of a Rolling Edit tool being used without holding the Alt or Option key?

Using the Rolling Edit tool without holding the Alt or Option key allows for simultaneous trimming of both the video and audio portions of a clip while keeping their linkage intact. This means that any adjustments made to the timing of one end of the clip will cause an automatic adjustment at the opposite end, maintaining synchronization and ensuring that the transitions remain fluid. This capability is essential for preserving the overall structure of a sequence while making precise timing adjustments.

In contrast, the other actions that involve isolating audio or video, deleting clips, or disregarding linkages does not apply in this scenario, as the Rolling Edit tool's primary function—when used correctly without additional key presses—focuses on maintaining the linked relationships between audio and video tracks.
