How to add on mouse hover effect in Word 2010 addin

Question

I wish to add text to the bottom of the font hover menu in word add-in:

But i cant find any documentation regarding this specific menu.

ADDED

My goal is to get an onmousehover effect while hovering on selected text, and since Selection doesnt provide any event i figured that the mini menu could be my solution.

That's called Word Mini Toolbar (naming is important to get the right search results - tip, always find adequate names:).

Anyway I think you're out of luck, I've never seen anything related to that (I know how you can change the context menu, that's no problem). And frankly it doesn't seem very likely, as that seems like a 'cute little' toolbar that's specifically formatted to fit small format, size/looks.

Check this MS link Developer Overview of the User Interface for the 2007 Microsoft Office System

And somewhere inside it says

You cannot modify the Mini toolbar programmatically.
