# The Mouse

To select a clip or other object, or to enable a menu button, click that item. Some functions are pressure-sensitive, such as the brush density in Paint, and the rate of change when dragging in numeric fields and sliders. When using the mouse, there are three levels of pressure.

Button | Pressure/Result
--- | ---
Left | Light: produces the slowest rate
Centre | Medium: yields a medium rate
Right | Heavy: produces the fastest rate
