Re: Extended Tool Tips

I don't think there is an official way to do it.

From the document:
    http://developer.apple.com/documentation/DeveloperTools/Conceptual/IB_UserGuide/AdvancedTechniques/chapter_9_section_6.html

It appears Cocoa supports only the basic form:
    "For Carbon controls you can specify both a simple tool tip and 
an extended help description. You use the Help field to specify the 
basic tooltip that appears when the user hovers the mouse over a view 
and you use the Extended Help field to provide an extended version of 
the tooltip that appears when the user presses the Command key. Cocoa 
controls support only the basic tool tip information."
