Tooltip Text on Views

I have some views I would like to have tooltips on. What is the magical combo of keys and values to make that happen?

Right now there isn’t really a magical combo of keys. We had tooltips for a long while but we encountered problems with tooltip display and placement that could cause serious usability issues, so we have removed them until we can take the time to do them right.

I don’t believe tooltips are planned for 8.0.
