'Declaration Public ReadOnly Property KeyActionMappings As TrackBarKeyActionMappings
public TrackBarKeyActionMappings KeyActionMappings {get;}
The KeyActionMappings property provides access to the control's mechanism for handling keyboard input from users. All keystrokes for actions such as selection, navigation and editing are stored in a table-based system that you can examine and modify using this property. Through the KeyActionsMappings property, you can customize the keyboard layout of the control to match your own standards for application interactivity.
For example, if you wanted users to be able to change the value by pressing the F8 key, you could add this behavior. You can specify the key code and any special modifier keys associated with an action, as well as determine whether a key mapping applies in a given context.
