Cognos8.2-Report studio: "Hint-windows" on drill-through

[Sunchaser]

Hi all,

I still haven't discovered the meaning of the functionnality available with the tab "Label", in the window where we can define the drill-through properties.
As it seems to be possible to use "advanced" methods, as conditions and dynamic source type, I'd really like to know how / when it works
(please, remind that I'm only using the PDF format for the reports)

In fact, I'd like to have a "hint-window" when the mouse is over a "object" containing a drill-through property (and particulary when the target is a bookmark), the same way we can see a small "hint-window" (with the URL) when the mouse is over a Hyperlink (even in a pdf report).

Is it possible ?
How can I get that working ?

Thx.
