Using the controls

Knobs

Basic use of the knobs is to click on them and drag the mouse up and down. However you can obtain different results by holding keys as follows:

Shift : Values change more slowly as you move the mouse.
Command : The knob assumes its default position.

Sliders

Sliders behave similarly.

Shift : Values change more slowly as you move the mouse.
Command : The slider assumes its default position.

Name/value display

As you move the mouse around the interface, the name and current value of the control currently under the mouse is displayed in the top right of the window. This area also provides tooltips for buttons.
