Review presents your selection as a clean, readable script, exactly what your client will see. The total runtime sits at the top, and each group shows its own. To listen or watch the video, just hit play. You can also click on specific sentences to skip around. The filter buttons let you read All selects, Must have only, or Maybe's only. That filter matters: it's the same one that decides what each export contains. So if you export on Must have only, that's what lands in your timeline.
