need help with editing audio? (simple question)

hey guys, I am new to Toon Boom. Anyways,

when I import a sound file, I want to cut out the middle in certain places. for example if the sound file has a keyboard sound effect at the beginning, then 10 seconds are silent, and then there is another keyboard sound effect, I want to be able to grab that 10 seconds and delete it. I tried to left click select the area i wanted to delete, but nothing happened when i tried to delete it. Hopefully it’s possible to do this, if not a way to do this otherwise would be appreciated, thanks.

Double-click on the layer name to open the sound editor.
