As your project is playing, listen to the audio and watch the play cursor in the timeline.

When you're ready, press the Y key on your keyboard and notice that the audio from the selected track is added to the timeline at the cursor position.

Keep pressing Y as desired to create events, and feel free to experiment a little. You can always edit the events later if you don't get them in quite the right places.

When you are ready to continue, click the Next button.
