Menu Link popups

Hi All,

I am trying to set up a simple menu "Glossary Items". Each of the glossary items is a simple node with a little bit of text. I just want to click a link in that menu and have the corresponding node popup to quickly give the definition.

This seems like it would be entirely possible, but I am not finding documentation within the forums to explain how I should go about doing this. Any help would be greatly appreciated.

Thanks so much!
