In that case either the business logic for the Help mode belongs in the 
event listener for the corresponding events for the elements in the first 
place, or entering/leaving Help mode should add/remove the respective 
listeners.  The latter may require native support for DOM3+ Events or an 
emulation thereof because order may matter.

You do not have to.

No, but it may be easier to place a ring marker "behind" (below, in the same 
stacking context) the widget to be marked, or IOW the widget on its marker.

You will need to implement the business logic of the Help mode in any case.
