</gallery>Similar to how we do cut (or copy) paste a selection of text in a text document, we can cut (copy) and paste a selection of audio in an audio file in Audacity. To delete a part of the track, we can select the area of track we wish to delete as shown in first image above and then press '''delete''' key on keyboard to delete. To move a part of audio to another place in same track or to another track, we need to select it first as we did before and then click on cut icon on the toolbar as shown in second image. Then the same audio can be pasted by clicking on paste icon on the toolbar as shown in third image above. The usual keyboard shortcuts for cut(<code>'''Ctrl+X'''</code>), copy(<code>'''Ctrl+C'''</code>) and paste(<code>'''Ctrl+V'''</code>) will also work on Audacity. Once you are done with editing, the final audio can be exported to any audio format from the Menu by clicking on File->Export and then Save.
