The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
This was a great purchase - it really made my kid's summer, and it's a such a great quality product. It know it will last for year's to come!
It used to be a struggle to tear my kids away from their tablets and video games, but with this amazing new playest, all of their friends come over and everyone plays outside for hours at a time.
