How do you trim and play multiple parts of a video?

You're able to trim multiple parts of a video and play them continuously. Here is how: 
Highlight a video on Timeline and click the Pen button. Under the preview window, click the  button and 2 markers will appear. Then drag the markers to set the segment you need. To trim another segment, move to another position of the video, and click the  button again to set a segment. Repeat this process to trim more segments you want. 

Tips: 1. Click the  button to set the beginning and ending time accurately.
           2. Click the  Button to preview the trimmed segments continuously. While previewing trimmed segments, the video cannot be trimmed.

To delete a trimmed segment, click it and then click the  button.
