# How do I add chapters with timestamps?

Select the text where a chapter should start and mark it (⌘⇧M) — the title comes from your selection. Chapters export as timestamp lists for YouTube and for Podcasting 2.0.

**Where:** Voice Editor, and the chapters layer in the Studio.

![A chapter is made two ways — from a selected sentence, and by clicking '+ Chapter here' between paragraphs with nothing selected. The default 'Chapter 1' is renamed by double-clicking its title, and the whole section folds away by clicking the thin bar on its left.](https://mubert.com/tools/cast/docs-media/chapters.mp4)

Chapters are anchored to the words you attached them to, not to a clock time. That is what keeps them right after you cut two minutes of filler out of the middle: a timestamped chapter would now point at the wrong moment, while yours still points at the sentence you chose.
