What happens when you use the E key while adding markers?

Using the E key while adding markers is designated to mark the start of a segment in video or audio editing software. This functionality is particularly useful for editors as it allows for efficient organization and segmentation of content. By marking the start, it sets a clear point where a specific segment begins, enabling better navigation and management of sequences.

For editors, understanding the significance of this action aligns with the broader workflow of editing, where delineating parts of footage or audio is crucial for creating a coherent final product. The use of markers to define the beginning of a segment aids in planning the structure of a project, whether that's for a rough cut, scene selection, or precise timing in post-production.
