I need to control my option lists via the keyboard (for accessibility). Since I need the key navigation sequences to be the same on FF, IE, and Safari, I cannot rely on the 'accessibility' attribute.
How can I make a HTML option list 'drop down' to show its items when I tab to the option list? And then, how can I make each option list element appear as if the mouse has moved to it when I hit the tab key successively to move through the list items?
Thanks in advance.
