What is the effect of utilizing the Track Select Backward tool?

Utilizing the Track Select Backward tool in a video editing software like Adobe Premiere Pro allows you to select all clips located to the left (or backward) of your current position in the timeline. This is particularly useful when you want to make bulk adjustments to multiple clips, such as moving or styling them, without having to select each one individually. By selecting all clips backward, you can easily reorganize your sequence or apply effects as needed, streamlining your editing workflow significantly.

The other choices reflect functionalities that do not align with the purpose of the Track Select Backward tool. For example, cutting clips, applying effects, or locking tracks are separate functions that cater to specific editing actions within the timeline. Each of those options represents a different editing tool or command, which is not the focus of the Track Select Backward tool's capabilities.
