_tooltip

Add a tooltip to the received HTML value -- Function

When you have a title, or some other short text like that, you sometimes want a "tooltip" -- a little pop-up -- with a better description of what it means. This function lets you add that.

Since _tooltip is a function, you have to use it inside a QL expression, like this:

[[""My Thing"" -> _tooltip(""My Thing is a special sort of Thing"")]]

In the long run, you will be able to describe a tooltip without using a QL expression, but for now, this is the way to do it.
