Tooltips are displayed for each wedge and button on a wheel as the you hover the cursor over them. Tooltips appear below the wheel and identify what action the wedge or button performs if you click it.
Similar to tooltips, tool messages are displayed when you use one of the navigation tools from a wheel. Tool messages are displayed over the Viewer window to provide instruction for using the active navigation tool. Like tooltips, you can turn tool messages on or off in the SteeringWheels preferences.
Disabling tool messages only affects the messages that are displayed when using the Full Navigation wheel.
