To add tracks in Adze, activate the Add Track tool by choosing it from the Tools menu or by pressing A.
To add a new track, select the Add Track tool and click the mouse at the location where you would like the first track point to be placed. Adze will create a new track containing one point before automatically switching to the Edit Point tool so that you can extend it with further points.
To remove a track, click on it in the track list and press the Delete key. You can also right-click on it and select Delete. Tracks will also be removed automatically if you remove all their points.
