+- on all browsers you can scroll: dragging the cursor, mouse wheel (speed customizable), keyboard navigation (cursor keys, pagup/down keys, home/end keys)
+- scroll is smooth (as modern tablet browsing), speed is customizable
+- tested for all major browsers but with extended support, including IE6, Safari on Mac and IE10 preview!
