What keyboard shortcut selects all clips in the timeline?

The keyboard shortcut that selects all clips in the timeline is Control/Command + A. This combination is a standard shortcut in many applications, including video editing software like Premiere Pro, where it has been designed to enhance workflow efficiency. By pressing Control/Command + A, users can quickly select all the elements present in the active window, which in this case is the timeline containing various clips. This capability is especially useful when you need to perform bulk actions, like moving, deleting, or editing multiple clips simultaneously, thereby streamlining the editing process.

The other options do not offer the same functionality: some might be associated with different commands or actions but do not uniformly select all items. Understanding the significance of shortcut keys not only improves productivity but also aids in mastering the software.
