# Operating Ring Slide Controls

When you set a ring slide control to any mode other than indicator mode, you can change its selected item from the keyboard or with the mouse.

You can operate a ring slide control from the keyboard in the following ways:

- Press the up arrow key to select the previous ring slide control item.
- Press the down arrow key to select the next ring slide control item.

You can operate a ring slide control with the mouse in the following ways:

- Click on and drag the needle—for circular controls like knobs—or the slider—for slide controls—to change the value of the control.
- Click on scale labels to set the control to the item corresponding to the label.

If the control mode of the ring slide control is hot or validate, a commit event is generated when you change its selected item.
