jQuery Keyboard Navigation plugin
This plugin allows you to navigate a set of links layed out in a matrix from keyboard:
[_ITEM_] [ item ] [ item ] [ item ]
[ item ] [ item ] [ item ] [ item ]
[ item ] [ item ]
The rows should have the same vertical offset. You can mark one element with .selected class, or the first one will be selected.
Enter key replaces window.location.href with the current href value.
Usage:
$('#navigation a').keynav();
This will enable keyboard navigation for the links in #navigation container. If you need to have some control on the state of plugin you can pass the additional function as a single parameter:
$('#navigation a').keynav(function(){
return window.keyNavigationDisabled;
});
Note: If the function passed returns true - keyboard navigation stops.
