Aspects for allowing adjustment of a setting via a slider bar displayed on a graphical user interface are provided. These aspects include providing a slider bar control button for the slider bar, and integrating fine and coarse adjustment control into the slider bar control button to allow precise manipulation of a value for the setting. The provision of a slider bar control button includes providing a thumbwheel control button with a central area for coarse adjustment control through repositioning of the thumbwheel control button, a top button substantially adjacent and above the central area for fine adjustment control to increase a setting value by a predetermined increment, and a bottom button substantially adjacent and below the central area for fine adjustment control to decrease a setting value by a predetermined increment. Alternatively, providing a slider bar control button includes providing a three section bar with a first section for coarse adjustment, a second section for fine adjustment up, and a third section for fine adjustment down. In yet another alternative, providing a slider bar control button includes providing a zoom control button that allows adjustment to a scale displayed for setting values and responds to separate selection interface means to increase and decrease the scale.
