Scroll wheel, trackpads, and the Magic Mouse. Some mice come with a scroll wheel. Turning this wheel on the Y-axis will cause the window to zoom in or out, with the zoom focused at the mouse pointer. Turning the scroll wheel on the X-axis will scroll the window normally. Some mice do not support turning the wheel on the X-axis. Trackpads and other devices like the Magic Mouse use finger gestures in place of a scroll wheel and can also be used to zoom in and out or to scroll normally.
Selecting and editing a single track/channel. For stereo files or files with more than two tracks, hold down the Command key while clicking in the appropriate channel to select that channel. Clicking anywhere in the view automatically selects all channels.
