In this case I would use the 'find' function. If you're restricting menus launch it from a command button (code 'DoCmd.RunCommand acCmdFind' in the button's on click event). This should do exactly what you want, but you will have to type the value you are looking for in.
I know that it's not exactly what you're trying to achieve but it does work and very well too. In my book, simplicity is king! Robbo ;-)
