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 and drag the needle for circular controls like knobs to change the value of the control.
  • Click and drag the slider for slide controls to change the value of the control.
  • Click 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.
