in the $userinfo of the list, put code like:

[con(lst([your list name],mouseover(kMLine),[your additional info]))]

the additional info needs to be in the list definition, even though it is not displayed in your list.

I use this in my application for the same purpose you want to use it for.

PS sorry, should have explained, this puts the data into a statusbar on my window, in which the information is displayed.
