Is is possible to copy & paste sections of audio?

I'd like to take some of the the audio from the middle of the video, and copy it to the end during the closing credits. Is it possible to do this?

First, unlink audio from video with a right-click on its track and UNlLINK FROM VIDEO.

Then split out the audio section desired. Right-click | COPY

Move the cursor to the end section and, in the audio track, right-click | PASTE INSERT.

<ctrl-c> can also be used to copy, and <ctrl-v> to paste.

Thanks!
