Report ToolBar Help

In a ToolBar, I added a ‘contextual’ report: in Action, I set text in a Report Label to inform the user what he’s doing.

Earlier today, I was wondering about adding another ‘contextual’ help, but I do not found Got Focus / Lost Focus or MouseEnter / MouseExit or…
Yes, I read: “Mouse events”.
Yes, I saw “HelpTag”.

Am I wrong or is it possible to do that ?
(and if it is possible, how can I do that ?
