No "display:none" is used (was used before) in order to make the submenus transition, because "display:none" negates any attempt to define transitions. There's actually a 2px thick invisible submenu that you've probably moused over, causing the invisible submenu to gain focus. I've fixed this by setting its border width (where the 2px comes from) to zero.

At any rate, using navigational keys is a whole different mechanism that involves HTML attributes. I don't recall how it's done. There's "tabindex" but making it work with the current g-contest, which relies on css :hover state, is pretty difficult. At any rate, the adjustments made to the css mentioned in the previous paragraph should have fixed the problem. clear the css cache (I use this url) and see how it goes.
