Display the resulting HTML in a "pop up" on top of part of the current page

[BarrySmith]

I have markdown text in the form like

fddfsfd dfssdfdfsfddfs

link to 1/4 a page of markdown

dfdfdfsdfsdfsdfs sfdfsdfsdfsdfs link to another 1/4 a page of markdown

etc.

I would like that when you click on the "link" rather than jumping to a new page that displays the markdown it opens up one of those light-weight popup windows (with the x in the upper right corner) that displays the markdown (as html) on top of the current page.

Is there any way to do that using display-markdown or a way to add it as a feature. Sorry I am really unfamilar with how these light-weight popup windows work.

Thanks
