#### 3.25.40.3 scrolling

X and Y axis scaling in both 2D and 3D graphs can be adjusted using the mouse wheel. <wheel-up> scrolls up (increases both YMIN and YMAX by ten percent of the Y range, and increases both Y2MIN and Y2MAX likewise), and <wheel down> scrolls down. <shift-wheel-up> scrolls left (decreases both XMIN and XMAX, and both X2MIN and X2MAX), and <shift-wheel-down> scrolls right. <control-wheel-up> zooms in toward the center of the plot, and <control-wheel-down> zooms out. <shift-control-wheel-up> zooms in along the X and X2 axes only, and <shift-control-wheel-down> zooms out along the X and X2 axes only.
