What does the track forward tool do in a video editing timeline?

The track forward tool in a video editing timeline is designed to streamline the editing process by allowing the user to select a specific clip along with all subsequent clips to its right in the timeline. This is particularly useful for making edits or adjustments to multiple clips simultaneously, ensuring that you can easily manipulate or delete sections of your timeline without having to select each clip individually. By selecting a clip and everything that follows it, the tool enables a more efficient workflow, especially in complex projects where a large number of clips may be present.

In contrast, other options present different functionalities that don't align with what the track forward tool does. Selecting all clips in the timeline would encompass everything and not just a specific section following a chosen clip. Selecting everything to the left would work oppositely and might be less intuitive for many editing tasks. Finally, only selecting the audio track associated with a clip would focus solely on the audio element, neglecting the visual components and overall project organization that the track forward tool is designed to facilitate.
