After Mr. TLama have answered my last question (How to trap the TTN_LINKCLICK notification?) one point went unanswered because it was not asked :)
How to identify each link I clicked on the balloon, if there are more than one link?
I want to be able to include more than one link in the balloon and to respond to clicks differently.

The notification has no parameters, so you don't know which link was clicked. The moral: If you need more than one link, consider a more versatile interface than a tool tip, such as a toast notification or a dialog box.
