+### useBothWheelAxes
+When set to true, and only one (vertical or horizontal) scrollbar is visible then both vertical and horizontal scrolling will affect the scrollbar.  
+**Default: false**
+
+### useKeyboard
+When set to true, the scroll works with arrow keys on the keyboard. The element is scrolled only when the mouse cursor hovers the element.  
+**Default: true**

+### suppressScrollY
+When set to true, the scroll bar in Y axis will not be available, regardless of the content height.  
+**Default: false**
+
+### scrollXMarginOffset
+The number of pixels the content width can surpass the container width without enabling the X axis scroll bar. Allows some "wiggle room" or "offset break", so that X axis scroll bar is not enabled just because of a few pixels.  
+**Default: 0**

+When set to true, it uses `innerWidth` and `innerHeight` for the container size instead of `width` and `height`. When your container element has non-zero padding and the scrollbar layout looks weird, this option can be helpful.  
+**Default: false**

-This plugin supports old IE browsers in the **minimum** range. The plugin is tested in IEs >= IE6 and works(not well, but works).
+The plugin would work in IEs >= IE9 (not well, though).
