Selecting Tracks and Segments of Tracks
Now let’s learn how to select tracks and parts of tracks. Audacity supports the usual editing functions computer users are used to—copy and paste, delete, select, and so on, but it will drive you crazy if you don’t learn how to do them the Audacity way. A nice feature of Audacity is that it supports keyboard shortcuts for nearly all functions, so you can use the mouse or keyboard.
First, make yourself a new recording or import an existing audio file by selecting File > Import so you have some tracks to experiment with. Be sure the Selection tool is active. If you’re using the Multi-Tool, move it up or down until it changes into the Selection tool, which looks like a little I-beam.
