Using both keyboard and mouse to navigate dropdown menu

[hjre]

Hi,
I hope you can help me out here; I'm looking for a script (or anything else, in fact) so a disabled person can navigate through a dropdown menu by the use of the keyboard... key arrow-down/-up: navigating up & down in the menu and enter-key to select. At the same time a "non-disabled' person should be able navigate the menu by the use of a mouse! If any of you know a script or a program in which you can make such a combining, I would appreciate hearing from you...
Best regards

If you can't use a mouse, you probably have to use a special browser, and you probably can't use JavaScript. To use <a> links with the keyboard, you can use the accesskey="" property,
