Discussion
In this mode, the cursor becomes a question mark, and help appears for any user interface item the user clicks.
Most apps don’t use this method. Instead, apps enter context-sensitive mode when the user presses the Help key. Apps exit context-sensitive help mode upon the first event after a help window is displayed.
