I would like to reproduce the kind of tooltips that Visual Studio provides through its 'Intellisense' component. Any idea how to summon a particular tooltip when the cursor hovers over a keyword? I know I could readily map all the keywords to tooltip phrases, but I have no clue as to how to get the hovering cursor to send some sort of message that it's time to display the mapped tooltip message.

There is a nice article on how to employ tooltips in a CRichEditView.
