- Use COMMAND in place of Ctrl in the bindings listed on this page.
- COMMAND-Wheel-Rotate (the equivalent Audacity binding on Mac for Zoom waveform in or out) will only work if you disable "Zoom using scroll ball while holding Command" (or similar) in the System "Mouse", "Universal Access" or "Accessibility" preferencess.
- Alternatively, hold both COMMAND and CONTROL while zoom scrolling.
- Click on any of the other Preferences sections in the above image to go directly to that Preferences page.
The image above is enlarged vertically from default sizing to show a list of all the available mouse bindings. In the default view you can either scroll to see additional bindings or enlarge the dialog by dragging downwards on its bottom edge.
Currently, mouse bindings are not configurable.
Most of the bindings are for click and drag gestures when using one of the Audacity tools. "Left", "Right" and "Middle" in the list refer to the mouse button to be clicked.
If your mouse has a standard scroll wheel or ball you can also use the "Any" gestures listed above for vertical or horizontal scrolling of tracks on the Audacity screen, or for horizontal zooming in or out on the mouse pointer. Horizontal scrolling and zooming using the mouse wheel or ball requires the SHIFT or CTRL key respectively to be held down.
On Mac Trackpads you can use two fingers to scroll horizontally, or pinch/expand to zoom the waveform in or out at the pointer position, without using a modifier key. Horizontal scrolling and pinch/expand should also work on most touchpads on Windows machines, but you may need to apply this horizontal scrolling modification or to install special drivers for your touchpad.
