How to tell Users that a Tooltip lies behind a Text/Textbox/Image, etc.?

Question

In my UI, I have a normal text headline that covers a block of checkboxes. Without further information I'm scared of users not knowing what to do with the window. My idea is to put a tooltip in the headline to give users information about the function of my window.

How do I make clear that there actually is a tooltip behind that headline? I don't 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)?

Answer 1

I'm a fan of using a dashed underline to indicate a tooltip.

Answer 2

A tool-tip is not the UI you are looking for

As you correctly state tooltip is suitable for information on a specific item. Not the intent of the whole UI. What you want to do is present an option for "in-line help" on the UI here are ideas on how to do this include interactive callout, embedded text or icon
