In my U.I. I have a normal text headline that covers a block of checkboxes but without further information I'm scared of Users not knowing what to do with the window. So my idea was to put a tooltip in the headline to give Users information about the funktion of my window. But how do i make clear that there actually is a tooltip behind that headline? I dont think people would normally hover over the headline so they would never get the information. Is there some sort of specific system to imply that there will be a tooltip over a control or text (like some special cursor)?
You can add a small info icon next to the header, so the user will know that there is more information hidden.
Hope that this idea help you!
