Slider Controls
To get an exact number from a slider control, where dragging the “thumb” results in big swings, either move it to a stop (left or right), then click on the slide bar itself, to get the thumb to move by 1 per click. Or, place the slider in the middle, and then click to the right or left of the “thumb”, exactly on the slide bar, then drag, and it will move up or down in value by 1 as you continue to hold the mouse pressed.
